If `a sin x+b cos(x+theta)+b cos(x-theta)=d,` then the minimum value of `|cos theta|` is equal to

If a sin x + b cos ( x+ theta) + b cos ( x-theta)=d , then the minimum of | cos theta| is equal to

The minimum value of a sin theta+b cos theta is:

If sin theta + cos theta = x , then the value of cos^(6) theta + sin^(6) theta is equal to

If a cos theta - b sin theta =c, " then" a sin theta + b cos theta is equal to

x = a cos theta, y = b sin theta .

Minimum value of 4x^2-4x|sin theta|-cos^2 theta is equal

If A = [(cos theta, sin theta),(-sin theta, cos theta)] and B = [(sin theta, - cos theta), (cos theta, sin theta)] , evaluate A cos theta + B sin theta .
