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...
What is sin(10 degrees)? What is cos(20 degrees)? What is sin(360), where 360 is in degrees? What is tangent of 765 degrees? How would you approximate the angle between \overrightarrow u = (3,-7) and \overrightarrow v = (2,2) in degrees?
Use the trig identity to find the value of other indicated hyperbolic function A value of sinh x or cosh x is given. Use the definitions and the identity cosh^2 x - sinh^2 x = 1 to find the value of Rewrite sin^4 x / 2 in terms of the first power of the cosine. ...
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...

Now we can combine the terms:1. The first term becomes: sin(B)sin(C)cos(A)−sin(B)cos(C)sin(A)2. The second term becomes: cos(A)cos(B)cos(C)−cos(A)sin(B)sin(C)3. The third term is: −cos(C)(cos(A)cos(B)−sin(A)sin(B)) Step 6: Final simplificationAfter ...
