" 8."cos[b log(x)/(a)]

int(cos(a+b log x))/(x)dx

Integrate (cos(log x))/(x)

If f(x)=sin(log x) then f(xy)+f((x)/(y))-2f(x)cos(log y)=(A)cos(log x)(B)sin(log y)(C)cos(log(xy))(D)0

If f(x) = sin x , the derivative of f (log x) w.r.t.x is a)cosx b)f' (logx) c)cos (log x) d) (cos(logx))/(x)

If f(x)=cos((log)_e x),\ t h e n\ f(1/x)f(1/y)-1/2{f(x y)+f(x/y)} is equal to a. "cos"(x-y) b. log(cos(x-y)) c. 0 d. "cos"(x+y)

(cos x)/("log"_(e)x)

(b) int_(1)^(3)(cos(log x^(2)))/(x)dx

If int(dx)/(cos(x-a)cos(x-b))=(1)/(A)[log((f(x))/(g(x)))]+c , then

if cos^(-1) ((y)/(b))= n log ((x)/(n)), then
