Let 0 leq theta leq (pi)/(2) and x=X cos theta+Y sin theta y=X sin theta-Y cos theta such that x^(2)+4 x y+y^(2)=a X^(2)+b Y^(2) where a, b are constants, then

If sin 7theta + sin 4theta + sin theta = 0, 0 le theta le pi//2 , then theta =

If sin theta=0.7, "then" cos theta, 0 le theta lt 90^(@) is यदि sin theta=0.7, तो cos theta, 0 le theta lt 90^(@) है :

If f(x) = {sinx , x lt 0 and cosx-|x-1| , x leq 0 then g(x) = f(|x|) is non-differentiable for

Find theta , 0 sin theta = 0.7071 .

Find theta , 0 cos theta = 0.9604 .
