  1. sec ^2x/tan^2x you're right tan^2x+1 / tan^2x use partial fraction tan^2 x / tan^2... could also express the given in sin and cos sec ^2x/tan^2x (1/cos^2 x) / [(sin^2 x)/cos^2 x] get the reciprocal of the denominator and...

  2. d(sec²(x)) = 2sec(x)d( sec (x)) = 2sec(x)[tan(x) sec (x)]dx = 2sec²(x)tan(x) dx The power rule... the function (2sec(x)) multiplied by the differential of the function, d( sec (x)). Since the function is a function of x, the chain rule multiplies...

  4. Remember that sec x = 1/(cos x), so multiply both sides of the original by cos x and you get: 1...2 cos x Multiply by sec x instead and you get: sec² x + 1 = 2 sec x Those give you a way to reduce squares of cos x or sec x for...

  5. sec ^2(x) = 2sec(x)*tan(x) sec (x) sec ^2(x)tan(x) = sec ^2(x)* sec ^2(x) + tan(x)*2sec(x)tan(x) sec (x) the first one is just the chain rule.. the second is the product rule.

  7. d/dx sec (x) = sec (x) tan(x) is correct. Also, d/dx tan(x) = sec²(x). Now use the product rule to find d/dx sec (x) tan(x): d/dx sec (x) tan(x) = sec (x) sec²(x) + tan(x) ( sec (x) tan(x...
