The quotient of sine by cosine at an angle is equal to the tangent at that angle.

Tan theta cos theta math. When the angle of a right triangle is represented by theta. For angles that have measure larger than 90 degrees or measure smaller than 0 that is with a negative measure the definitions are more convoluted. For an angle in standard position we define the trigonometric ratios in terms of x y and r. Cos θ as adj hyp and.

But we are using the specific x y and r values defined by the point x y that the terminal side passes through. Our math solver supports basic math pre algebra algebra trigonometry calculus and more. The sine cosine tangent and cotangent functions are written as sin theta cos theta tan theta and cot theta respectively. Free math lessons and math homework help from basic math to algebra geometry and beyond.

Sin θ as opp hyp. Sin theta y r cos theta x r tan theta y x notice that we are still defining. The functions sine cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functions. The parentheses around the argument of the functions are often omitted e g sin θ and cos θ if an interpretation is unambiguously possible.

Their usual abbreviations are sin θ cos θ and tan θ respectively where θ denotes the angle. Tan theta frac sin theta cos theta you can check that the two definitions of the tangent are equivalent. Students teachers parents and everyone can find solutions to their math problems instantly.
