Express tangent in terms of cosine
Webwe discuss the four other trigonometric functions: tangent, cotangent, secant, and cosecant. Each of these functions are derived in some way from sine and cosine. The tangent of x is defined to be its sine divided by its cosine: tanx = sinx cosx: The cotangent of x is defined to be the cosine of x divided by the sine of x: cotx = cosx sinx: WebTo use trigonometric functions, we first must understand how to measure the angles. Although we can use both radians and degrees, radians are a more natural …
