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...
Similarly, the cosine is defined as it is the trigonometric function which is equal to ratio of the length of the adjacent side to the length of the hypotenuse. There are six basic trigonometric ratios for the right-angled triangle. They are sin, cos, tan, cosec, sec, cot which stand...

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...
which are cosine(cos), sine(sin), tangent(tan), cotangent(cot), secant(sec), and cosecant(cosec). These functions are used in many Arduino projects like in robotics, different movements are dependent on certain angles. Similarly, in smart vehicles, the angle is needed in the parking ...
sin(x) is the ratio of the side opposite the angle and the hypotenuse, cos(x) is the ratio of the side adjacent to the angle and the hypotenuse, tan(x) is the ratio of sine and cosine Where is trigonometry used in real life? In real life, trigonometry has applications in many ...
The graphs of basic trigonometric functions- Sine and Cosine are given below:The domain and range of sin and cosine functions can thus be given as,sin θ: Domain (-∞, + ∞); Range [-1, +1] cos θ: Domain (-∞ +∞); Range [-1, +1]...
cos x = sin (π/2 - x) Cosine Formulas Using Sum/Difference Formulas We have sum/difference formulas for every trigonometric function that deal with the sum of angles (x + y) and the difference of angles (x - y). The sum/difference formulas of cosine function are, ...
What are the sine, cosine, and tangent of theta = 3pi / 4 radians? Given sin x = 3/5 and x is in quadrant II, what is the value of tan x/2? How do you solve for x in tan(x) + tan(2x) + tan(3x) = 0? Solve the following trigonometric function:4 sin^2(x) tan(x...
