`underset(x to 1)lim (1-x) tan(pix//2)`=

lim_(x to 1) (1-x)tan((pix)/2)

Evaluate : underset(xrarr1)"lim"(1-x)"tan"(pix)/(2)

Find the limits: (a) underset(x to 0)lim (1-cos x)/(x^2) (b) underset(x to 0)lim (tanx-sinx)/(x^(3)) (c ) underset(x to 1)lim ""(cos (pix//2))/(1-x)

underset(x to -2)lim (tan pix)/(x+2)+underset(x to oo)lim (1+1//x^(2))=

underset(x to 1)lim (tan^(2)pix)/(1+sec pi x)=

Value of the underset(x to -2)lim (tan pi x)/(x+2)+underset(x to oo)lim (1+1/x^(2))^(x) is

underset(x to 1)lim (3 sin pix-sin 3pix)/((x-1)^(3))=
