((1) / ((sec x) ^ (2) - (cos x) ^ (2)) + (1) / ((cos ecx) ^ (2) - (sin x) ^ (2))) ( cos x) ^ (2) (sin x) ^ (2) = (1- (cos x) ^ (2) (sin x) ^ (2)) / (2+ (cos x) ^ (2) (sin x) ^ (2))

cos x+sec x=2

If cos((pi)/(4)-x)cos2x+sin x sin2x sec x=cos x sin2x sec x+cos((pi)/(4)+x)cos2x then possible value of sec x is

If f(x)=cos ^(2) x+sec ^(2) x , then

Evaluate the following integrals : int (sec x + 2 cot ^(2) x + cos^(2) x )/(cos x ) dx

show that (cos (x/2) + sin (x/2))/(cos (x/2) - sin (x/2))= sec x +tan x

int sqrt((cos ecx-cot x)/(cos ecx+cot x))*(sec x)/(sqrt(1+2sec x))dx

The value of the expression (sin x+cos ecx)^(2)+(cos x+sec x)^(2)+(tan x+cot x)^(2)
