Sine (sin) and cosine (cos) are fundamental trigonometric functions that play a vital role in various areas of mathematics, physics, and engineering. The sine of an angle in a right-angled triangle is defined as the ratio of the length of the side opposite the angle to the length of the...
The sine of one of the angles of a right triangle (often abbreviated “sin”) is the ratio of the length of the side of the triangle opposite the angle to the length of the triangle’s hypotenuse. The cosine (often abbreviated “cos”) is the ratio of the length of the side adjacent...
Hint:Express ${{270}^{\circ }}\text{ into }\left( {{270}^{\circ }}+\theta \right)$ . Then we should use the following two identities for sin and cosine respectively, $\sin \left( {{270}^{\circ }}+\theta \right)=-\cos \theta \text{ and }\cos \left( {{270...
