For a right-angle triangle, the trigonometric functions are used to give the relation between two sides of the triangle and one angle of the triangle. Three primary trigonometric functions are sine, cosine and tangent.Answer and Explanation: The given expression is, {eq}\cos 21\cos 39 - \...
The sine of zero degree is mathematically written as $\sin{(0^\circ)}$ as per sexagesimal system and its exact value is equal to zero. Therefore, the value of sine of zero angle is written in the following form in mathematics.
x≈0.785+2kπ and x≈3.927+2kπwhere k is any integer.Solution 2: AlgebraicTo find the exact solution, we set f(x)=g(x) and solve the resulting equation algebraically.sin x=cos x Equate functionsSince the numbers x for which cos x =0 are not solutions of the equation, we can ...
