Was never taught number theory in school.....I feel inferior when its being discussed..... Any recommendable text?

No treading of insults plzz,,maths problems is all we solve here , tnx .

Durentt:
Yet u criticize mathematician nd compare dem to economists, why dont you use ur dumb engineering brain nd solve all ur math problem. Crystallised creatinous fvcktard

sorry bro, i only wanted to hit dat iidiot. Carry on, i hail the great MATHEMATICIANS

Pls help - integral 1/1-x^2 multiplied by sqrt(1-x^2)dx. Agentofchange1,Thankyoujesus and others

ok bro make ur question clear or upload a pix

boss, i cant snap with my phone. Pls note: Multiplied by means 'dot', sqrt means square root, 1-x^2 means, 1-xsquared.

Omo FUTA, I get u die... MTS101 assignment. God dei my brother, Mr Afolabi no go kill us

ABI nah,,,, I no no say u go talk ham oooooo........................................ #futarians

ok ,try use the parenthesis properly,

is it integral 1/[(1-x^2)sqrt(1-x^2)]dx ?

Somebody please help....

[I] A surface consists of parts of the planes x = 0, x = 2, y = 2 and z = 3 - y in the region z greater than equal to zero. Apply Stokes' theorem to evaluate [''surface integral'' curl F. ds] over the surface where F = 2xi + xzj + yzk where S lies in the z = 0 plane.

[II] Find unit vectors normal to the surfaces x^2 + y^2 - z^2 + 3 = 0 and xy- yz + zx - 10 = 0 at the point (3, 2, 4) and hence find the angle between the two surfaces at that point.

No, the closed bracket is not included.
Sqrt of (1-x^2)dx is at the top of the former...

OK , That simplify to 1/sqrt(1-x^2) dx =arcsin(x) +c

since they are same, use law of indices, you are left with "negative half power", apply the negative law of indices, after that, go with either of; X=sin¤ or cos¤.

pls cld you show the workings?

if u have a^(1/2) /a , what does it simplifies to ?

agentofchange1:

(a)^-1/2

good, which is = 1/a^1/2 right?

hope u see wer am going with this

ayokunlei:


(a)^-1/2

agentofchange1:

ohh... Yes, thank you. The thing is, when solving small problems, I tend to make mistakes at times, thanks for the explanation... kudos. ThankyouJesus. Thanks

any day bro, kip solving

ohh... Yes, thank you.

How many digits does 3⁵⁰⁰⁰ have?

Madmathecian:
How many digits does 3⁵⁰⁰⁰ have?

The answer should be:

5000log3

which is 2385.60627...

Since there can only be whole digits(always round up), the answer is 2386

Explanation:

3⁵⁰⁰⁰ == k x 10ⁿ

where n represent the number of digits if 0.1< k < 1

finding log of both sides and simplifying:

5000log3 = logk + nlog10

n = 5000log3 - logk

since logk is inconsequential since logk <<< 5000log3, we can ignore first.

n = 5000log3
n = 2385.60627...

Note that -1 lessorequal logk lessorequal 0

Therefore we can only round up our answer

n = 2386


Also, by extension:

logk = 5000log3 - 2386

k = 10^{(5000log3 - 2386)}
k = 0.40389976...

It follows that 3⁵⁰⁰⁰ = 0.4039 x 10²³⁸⁶

Hello house,please check this out.

1.If we are to select two out of 4 boys and 5 girls,how many of them will be girls?

2.If 6 letters are arranged in 6 different enveloped,what is the probability of picking a particular letter?

Invalid question. Number of girls is either 0, 1 or 2

Answer = 1/6

Find the distance from the point (2,3) to the line containing the points (−2,−1) and (5,4).

(1)what is the real application of mathematics in our live?

(2) prove that:
a. Sin^3 x = 1/4(3sinx - sin3x)
b. Find 2nd derivative of:
y = cos^3 x

Mathematics is full of beautiful patterns that can be used in our everyday lives.Its concepts covers all works of life depending on what you are talking about.So if there is no mathematics there is no science and commercial aspects of life.It makes you to think critically and create something out of nothing.
2.To prove that sin^3 x=1/4(3sinx-sin3x),apply the differentiation from the first principle.
3.y=cos^3 x apply the algebraic rule of the derivative twice or you can still use the derivative from the first principle.

Madmathecian:
Find the distance from the point (2,3) to the line containing the points (−2,−1) and (5,4).

Do you mean the shortest distance?

If yes then:
The shortest distance to a point is across a perpendicular line to the line towards the point.
#1 - Equation of the line perpendicular to the line is calculated
#2 - Point of intersection of the lines is found
#3 - Distance between the point of intersection of the lines and the point (2,3) gives answer

#1
(y-4)/(x-5) = (4--1)/(5--2)

y-4 = 5/7(x-5)

7y = 5x + 3

m= 5/7
-1/m = -7/5

(y-3)/(x-2) = -7/5

y-3 = -7/5(x-2)

5y = -7x+29

Mathano:
When is a system of equations said to be consistent and inconsistent

A system of equations is said to be consistent if it has one solution(unique) or many solutions while it can be inconsistent if it has no solutions.
