Math  Solving for Trig Equations
For the following equation, why cannot I not solve it? I keep getting an error.  2cosx  3 = 0  I first isolated for "x" 2cosx3 = 0 (2cosx/2) = (3/2) x = cos^1(3/2) x = error? why?  My textbook answer: 30 and 330 degrees

prove the identity (sinX)^6 +(cosX)^6= 1  3(sinX)^2 (cosX)^2 sinX^6= sinx^2 ^3 = (1cosX^2)^3 = (12CosX^2 + cos^4) (1cosX^2) then multiply that out 12CosX^2 + cos^4  cosX^2 + 2cos^4 cos^6 add that on the left to the cos^6,

calculus help again
if f'(x)=cos x and g'(x)=1 for all x, and if f(0)=g(0)=0, then the limit x>0 fo function f(x)/g(x)= okay, so f(x)=sinx g(x)=x and the f(0)=g(0)=0 is also satisfied and equals o. so the limit x>o of sinx/x= is the answer

Integration?
Sorry, i have a load of questions on integration... thanks for any help provided! Evaluate the integrals: limit 0 to pi/4 ∫ [sec^2x]/[5+tanx] dx limit 0 to pi/6 ∫ [3cos3x]/[3+sin3x] dx limit 0 to 3 ∫ [2x1]/[x^2x+1] dx

Explain how to do this with steps please. 1. Simplify cos(xy)+cos(x+y)/cosx I did some of these so far, don't know if it is correct. Formula: cosxcosy= cos(x+y)+cos(xy)/2 cos(xy)+cos(x+y)/cosx =cosxcosy/2cosx
