$\sin{t}$; $\cos{t}$; $\tan{t}$

Work Step by Step

Cosecant and sine are reciprocals of each other so $\dfrac{1}{\csc{t}}=\sin{t}$. Secant and cosine are reciprocals of each other so $\dfrac{1}{\sec{t}}=\cos{t}$. Cotangent and tangent are reciprocals of each other so $\dfrac{1}{\cot{t}}=\tan{t}$. Thus, the missing expressions in the given statements (in order) are: $\sin{t}$; $\cos{t}$; $\tan{t}$
