Question

UpStudy AI · Accepted Answer

Sine is $$ \sin x $$, cosine is $$ \cos x $$, tangent is $$ 	an x $$, cotangent is $$ \cot x $$, and secant is $$ \sec x $$. It seems like you're asking about trigonometric functions and possibly their relationships or identities. Let's clarify the terms you've mentioned: 1. **Sine**: $$ \sin x $$ is the ratio of the length of the opposite side to the hypotenuse in a right triangle. 2. **Cosine**: $$ \cos x $$ is the ratio of the length of the adjacent side to the hypotenuse. 3. **Tangent**: $$ 	an x $$ (often written as $$ \operatorname{tg} x $$ in some regions) is the ratio of the sine to the cosine: $$ 	an x = \frac{\sin x}{\cos x} $$. 4. **Cotangent**: $$ \cot x $$ (often written as $$ \operatorname{ctg} x $$) is the reciprocal of the tangent: $$ \cot x = \frac{1}{	an x} = \frac{\cos x}{\sin x} $$. 5. **Secant**: $$ \sec x $$ (often written as $$ \operatorname{ec} x $$ in some regions) is the reciprocal of the cosine: $$ \sec x = \frac{1}{\cos x} $$. If you have a specific equation or identity involving these functions, or if you need help with a particular problem, please provide more details!
