int sin x cot^(3)x

int(cot x+cot^(3)x)/(1+cot^(3)x)dx

int cot x tan^(3)[(x)/(2)]

If (cot x+(cot^(2)x)/(2)+(cot^(3)x)/(3)+...+(cot^(99)x)/(99))+ int(1+cot x)(1+cot^(99)x)dx =-lambda[int cot^(2)xdx+int cot^(3)xdx+int cot^(4)xdx+...+int cot^(98)xdx] , then value of lambda is equal to

lim_(x rarr0)sin8x cot3x Lim sin8x cot3x
