Because you can draw a right triangle inside any triangle, you can also use trigonometric identities to find the height of a triangle. If you know the angle between the height and the hypotenuse of the triangle, you can set up the equation tan(a) = x / b, where a is the angle, x...
In trigonometry, the period of a function refers to the distance of a function's wave. Learn how to find the period of a trig function by exploring...
What is the value of the sin 15? opposite to the angle to the length of the hypotenuse in a right triangle. To find the sine of 15 degrees, we can draw a right triangle with one of the angles as 15 degrees. Using basic trigonometric ratios, sine theta = opposite side/hypotenuse. For...
