If x = pi/2, then csc(x) = 1 and cot(x) = 0; 1 + 0 = 1 if x = 3pi/2, then csc(x) = -1 and cot(x) = 0 1 = √ sec² u du = tanu +. C. = } x3 tan x³ + C. 40. For I = ⇒ f csc² x (cotx-1)3 dx, let u = cotx - 1 du= -csc² x dx. Then. I=- Sử du=-tu^ +C =-d (cotx − 1)+C. Oct 30, 2018 ... An algebraic method is the best way to prove (1+cot(x) ) / (1 + tan(x) = cot(x), let's look at a graph of 1+cot(x) ) / (1 + tan(x) - cot(x)=1sin(x)cos(x)=cos(x)sin(x).
