You can also get the "Reciprocal Identities", by going "through the 1"Here you can see that sin(x) = 1 / csc(x)Here is the full set:sin(x) = 1 / csc(x) cos(x) = 1 / sec(x) cot(x) = 1 / tan(x) csc(x) = 1 / sin(x) sec(x) = 1 / cos(x) tan(x) = 1 ...

= x csc-1x + ∫ (1 / tan u) (sec u tan u) du = x csc-1x + ∫ sec u du = x csc-1x + ln |sec u + tan u| + C (from the integral of sec u formula) = x csc-1x + ln |sec u + √(sec2u - 1)| + C (by trig identities) = x csc-1x + ln |x + √(...
If y = 0, then tan y= 0, hence the product sec y tan y is 0. Therefore, that product is never negative.(This theorem is referenced in the proof of the derivative of y = arcsecx.)Next Topic: Trigonometric identitiesTable of Contents | Home...
