Find the minimum value of 2costheta+1/sin theta+sqrt2tantheta , where theta is acute angle.

The minimum value of cos theta+sintheta+ 2/(sin2theta) for theta in (0, pi/2) is (A) 2+sqrt(2) (B) 2 (C) 1+sqrt(2) (D) 2sqrt(2)

Find the maximum and minimum values of 8costheta+15sintheta :

Find the minimum value of (sintheta+cosectheta)^(2)+(costheta+sectheta)^(2)

sintheta+costheta=sqrt(2)

Evaluate [(1+costheta)/sintheta]^2

Evaluate (1-costheta)^2+(sintheta)^2

Evaluate (1-costheta)^2+(sintheta)^2

sqrt(3)costheta+sintheta=2
