Help!!! Calculus Integral Question

I have to solve the following equation, a. Integral if (x)/ (1 + x^4) dx b. Integral from 1/6 to 1/2 of (csc (pi*t) * cot (pi*t)) dt I have to do u- substitution and we have not covered this in cl

Is √(a-1)² positive or negative (a≠1)

Positive because for any number n: (n*n) and (-n)*(-n) is always positive hence (a-1)^2 is always positives. Then the square root sign as written always refers to the positive square root of a numbe

(tan A +sec A - 1) / (tan A - sec A+ 1)= (1+sin A)/ cos A

Can anyone prove this identity for me?I will really appreciate it.-Use sec^2A-tan^2A=1 take the numerator secA+tanA-1= secA+tanA-(sec^2A-tan^2A)=(secA+tanA)-… now take (secA+tanA) as common =(secA+tan

Help Math question lots of works sorry 10 points for anyone who can do it all

Explain why no real numbers is a solution to the equation x+4=x+2 solve -41 ≤ 9x+ 13≤ 53 and graph the solution on a number line sorry i dont have a graph to show u guys but it says Use the graph b

What is the derivative of F(x) = 2x - 3/x by the Definition of a Derivative

Ive gone through it several times and havent been able to come out with the correct derivative, or its equivalent. The actual derivative by derivative rules is 2 - 3/x^2-I always hated these; if I cou

Math help please!!! 10 points!!!

Solve this system by elimination: 4x + 3y = 3/2 3x - 2y = -19/2 Thanks in advance!!!!:-)-4x + 3y = 3/2 3x - 2y = -19/2 (original equation) 8x + 6y = 3 (multiplied by 2 to get rid of fraction) 6x -4

Would anyone know how to solve this math problem

Show the work to solve |3x - 2| Describe the graph of the solution in words. if you guys cant solve it it would help allot if you could just describe the graph of the solution in words. thanks :]-

Pre Algebra is hard for me, but regular Algebra isn't

I think its quite weird, but I dont know. Is it just me? I think it may be my teacher, she makes it seem extremely hard, but when I do regular Algebra in my extra class, its so fun for me, and I reall

Find the derivative of the function

y=3+8x-6(squareroot x)/x-First simplify 6sqrt(x)/x to 6x^(.5)*x^(-1) = 6x^(-1/2) y = 3 + 8x - 6x^(-1/2) dy/dx = 8 + 3x^(-3/2) Jen-Best way to deal with root derivatives is to change it to whatever

Equilateral Triangle Question

How do I divide an equilateral triangle into 6,7 and 8 other equilateral triangles. Please help.... How do I divide it into 6,7 or 8 other equilateral triangles. I really dont have much time to answer

Calculus and coordinate question

The acceleration vector is a(t)=−4cos2t_i + −4sin2t_j + 1t_k The initial velocity is v(0)=i+k , and The initial position vector is r(0)=i+j+k Compute v(t) and r(t).-v(t) = antiderivative of accelera

When given the equation A=1000(1.08)^n, how would I solve for n when A is 2500? without using a graph.

be specific-1000 (1.08)^n = 2500 Divide both sides by 1000: (1.08)^n = 2.5 Take natural log of both sides, then solve for n: ln(1.08^n) = ln(2.5) n ln(1.08) = ln(2.5) n = ln(2.5) / ln(1.08) n = 11.
