Period of f(x)=(sin x+sin3x)/(cos x+cos3x) is (Value of e=2.72 and pi=3.14 )

The value of 2 sin 3x cos 2x is equal to

Consider the system of equations x cos^(3) y+3x cos y sin^(2) y=14 x sin^(3) y+3x cos^(2) y sin y=13 The value of sin^(2) y+2 cos^(2) y is

The smallest positive value of x (in radians) satisfyinig the equation (sin x)(cos^(3)x)-(cos x)(sin^(3)x)=(1)/(4)

What is the value of (sin^(3) x + cos^(3) x)/( sin x + cos x) + sin x cos x ?

If sin^(3)x cos3x+cos^(3)x sin 3x=3//8 , then the value of sin 4x is ___________

" Let " =|{:(cos x,,sin x,,cosx),( cos 2x,,sin 2x,,2cos 2x),(cos 3x,,sin 3x,,3cos 3x):}| then find the values of f(0) and f' (pi//2) .
