WebSince cot(x) is the reciprocal of tan(x), tan^2(x) = 1/cot^2(x). In step 4 we write cot^2(x)/cot^2(x) in place of 1, since this will give us a common denominator within the square root. In step 5, with the common denominator cot^2(x), we are able to combine the numerators into one fraction. WebIf f(x)=\begin{cases}\\ -2(x+1) \ if \ x \leq 0\\ k(1-x^2) \ if \ x > 0 \end{cases} then the value of k for which \int^1_{-1} f(x)dx=1 is; Prove the identity. \tanh(\ln x) = \frac{x^2-1}{x^2+1} It is known that J_-1/2(x) = (2/pi x)^1/2 cos x Show that J_3/2 (x) = (2/pi x)^1/2 (sin x/x - cos x), J_-3/2(x) = -(2/pi x)^1/2 (cos x/x + sin x).
