sin theta is equal to cos theta formula Sin theta a c csc theta 1 sin theta c a cos theta b c sec theta 1 cos theta c b tan theta sin theta cos theta a b cot theta 1 tan theta
Tan sin cos That is our first Trigonometric Identity Cosecant Secant and Cotangent We can also divide the other way around such as Adjacent Opposite Solution We know that sin2 2 sin cos We need to determine cos Let us use the sin cos formula cos 2 sin 2 1 Rewriting we get cos 2 1 sin 2 1 9 25

begin align 2 tan theta sec theta 2 left dfrac sin theta cos theta right left dfrac 1 cos theta right dfrac 2 sin theta cos 2 theta Start by simplifying the tan 2 theta angle tan 2 sin 2 cos 2 1
The easiest way is to see that cos 2 cos sin 2 cos 1 or 1 2sin by the cosine double angle formula and the Pythagorean identity Now substitute 2 into begin align 2 tan theta sec theta 2 left dfrac sin theta cos theta right left dfrac 1 cos theta right dfrac 2 sin theta cos 2 theta
