Best ResponseYou've already chosen the best response.1thanks thank you!!! \[\rm \sin \theta = \frac{ 1 }{ \csc \theta }\]\[\cos \theta =\frac{ 1 }{ \sec \theta }\]\[\tan \theta=\frac{ 1 }{ \cot \theta } = \frac{ \sin \theta }{ \cos \theta }\] these are the definition of sin,cos and tan cos is reciprocal of sec

Best ResponseYou've already chosen the best response.1so you can replace sec with 1/cos \[\huge\rm \frac{ \color{reD}{\sec} \theta \cos \theta }{ \sin \theta }\] \[\huge\rm \frac{ \frac{ 1 }{ \cos \theta } \cos \theta }{ \sin \theta }\] now find the common denominator of \[\frac{ 1 }{ \cos \theta }\cos \theta \]

Best ResponseYou've already chosen the best response.1well,hm common denominator is cos \[\frac{ \frac{ 1\cos^ 2 \theta }{ \cos }}{ \sin \theta }\] so multiply both terms by cos 1/cos times cos and cos times cos when you multiply same bases you should add their exponents so cos times cos = cos^2 and 1/cos times cos =1 tthat's how you get 1 cos^2 theta

Best ResponseYou've already chosen the best response.1now you must know this special identity \[\huge\rm sin^2 \theta+\cos^2 \theta =1\] solve this equation for sin^2 theta let me know what you get
