If θ is one of the acute angles in a triangle, then the sine of theta is the ratio of the opposite side to the hypotenuse, the cosine is the ratio of the adjacent side to the hypotenuse, and the tangent is the ratio of the opposite side to the adjacent side Solution: Given, cos (sec –1 x + cosec –1 x) By the formula, we know that; cosec –1 x + sec –1 x = π/Thus, cos (sec –1 x + cosec –1 x) = cos π/2 =Test your Knowledge on Trigonometry Formulas For Class Put your understanding of this concept to test by answering a few MCQs. We will now extend the definition of trigonometric ratios to any angle in terms of radian measure and study them as trigonometric functions. Trigonometric Sum and Difference Formulas. These Trigonometry Formulas are very useful for students from classwhich cover Pythagorean identities, product identities, cofunction identities (shifting angles), sum & difference identities A list of formulas in Trigonometry for classbased on the right triangle and the unit circle is provided below. Click ‘Start Quiz’ to begin! We will now extend the Trigonometric Formulas. The most important formulas for trigonometry are those for a right triangle.
