As `theta` increases from `0^(@)` to `90^(@)`, the value of `cos theta` is

As theta increases from 0^(@) to 90^(@) , the value of sin theta : -

Find value of cos(90+theta)

If cos theta + sec theta = 2 ( 0^@ letheta le 90^@) , then the value of cos 10 theta + sec 11 theta is

If (cos^(2) theta)/(cot^(2) theta - cos^(2) theta) = 3 and 0^(@) lt theta lt 90^(@) , then the value of theta is

If sqrt(3) sin theta - cos theta = 0 and 0^(@) lt theta lt 90^(@) , find the value of theta .

If sin theta+cos theta=sqrt(2)cos(90^(@)-theta) then value of cot theta is

If sin theta - cos theta =0, 0 le theta le 90^(@) then the value of theta is _____-

If tan^(2)theta - 3sectheta + 3=0, 0^(@) lt theta lt 90^(@) , then the value of sintheta + cos theta is:
