1+tan^2x proof

1+tan^2x proof-Let y = tan(x) Recall the definition of tan(x) as sin(x)/cos(x) Therefore y = sin(x)/cos(x) Use the quotient rule, which states that for y = f(x)/g(x), dy/dx = (f'(x)g(x) f(x)g'(x))/g 2 (x) with f(x) = sin(x) and g(x) = cos(x) Recall the derivatives of sin(x) as cos(x) and cos(x) as sin(x)Sep 18, 12 · tex\tan(2x) = \frac{2 \tan(x)}{1 \tan^2(x)}/tex There is the good response here, and I particularly agree with this because this generally makes the simplification a bit simple Don't forget that you have the function as the exponent of the another function!
