(cos3 theta)/(2cos2 theta-1)

(cos 3theta)/(2cos 2theta-1)=(1)/(2) if

(cos3theta)/(2cos2theta-1)=(1)/(2) if

(cos3theta)/(2cos2theta-1)=

The value of (cos3theta)/(2cos2theta-1) is equal to (a) costheta (b) sintheta (c) tantheta (d) none of these

The value of (cos3theta)/(2cos2theta-1) is equal to (a) costheta (b) sintheta (c) tantheta (d) none of these

The value (2cos theta-1)(2cos2 theta-1)(2cos4 theta-1)(2cos8 theta-1)=

((sin3 theta)/(sin theta))^(2)-((cos3 theta)/(cos theta))^(2)=a cos2 theta wherever it id defined.Then the value of a is

(sin3 theta+cos3 theta)/(cos theta-sin theta)=1+2xx sin2 theta

If sqrt(3)sin theta=cos theta, find the value of (3cos^(2)theta+2cos theta)/(3cos theta+2)

If (sec theta+tan theta)/(sec theta-tan theta)=5 , and theta is an acute angle, then the value of (3 cos^2 theta+1) /(3 cos^2 theta-1) is: यदि (sec theta+tan theta)/(sec theta-tan theta)=5 , तो (3 cos^2 theta+1) /(3 cos^2 theta-1) का मान ज्ञात करें जहाँ theta एक न्यून कोण है
