1. ### integral of sec ^8x square root(tan^3x)?

sec ^8(x) * √(tan^3(x)) dx = ∫ sec ^6(x) * sec ^2(x) * √(tan^3(x)) dx Note that 1 + tan^2(x... sec ^2(x) * √(tan^3(x)) dx Now let z = tan(x) => dz = sec ^2(x) dx = ∫(1 + z^2)^3 * z^(3/2) dz Now basically expand...

2. ### Can someone please help me with a trig proof? sec2x = ( sec ^2x)/(2- sec ^2x)?

sec (2x) = [ sec ^2(x)] / [2 - sec ^2(x)] Your first step would be to choose the more complex side. I'm... = 1 / cos(2x) Which, by definition is equal to RHS = 1 / cos(2x) = sec (2x) = LHS

10. ### if sec Θ=4/3, and Θ is a first quadrant angle, find the value of sin Θ and tan Θ, I am really having a hard

Hi, sec Θ is the reciprocal of cos Θ. csc Θ is the reciprocal...sin Θ. cot Θ is the reciprocal of tan Θ. If sec Θ=4/3, then cos Θ= 3/4. Since cosine = adjacent over hypotenuse...
