... it takes theratio"opposite/hypotenuse" and gives us an angle. Example: Sine Function: sin(30°) =0.5 Inverse Sine Function: sin-1(0.5) =30° On the calculator press one of the following (depending on your brand of calculator): either '2ndF sin' or 'shift sin'. ...
In order to find the period of a graph in general, first, find the period of the parent function, and divide that by the absolute value of the coefficient of the independent variable. In the case of sine functions, the parent function is sin(x), and its period is 2 pi. How do you...
Many of this cases have been there before the marriage. An example is one that drinks casually before marriage and then becomes an addict after. Usually he didn’t plan to be this way but he has had this issue before in his past and stress of life brought him back to the state of be...
A letter to the editor is presented in response to the issue regarding how to find the exact values for the sine of angles that are multiples of 18° without using double or triple angle formulas.WenjiangOswegoTuOswegoEBSCO_AspMathematics Teacher...
A wire goes to the top of the mast at an angle of 68°. How long is the wire? Step 1 The two sides we are using are Opposite (70) and Hypotenuse (w). Step 2 SOHCAHTOA tells us to use Sine. Step 3 Write down: sin 68° = 70/w Step 4 Solve: The unknown length is on...

Haversine of a central angle, which equals the spherical distance divided by the radius of the sphere, can be calculated using the haversine formula: We can transform this formula using the first definition of the haversine function and rearrange it such that d is on the left side: Now, it...
The value of tan 30 degrees can be calculated by constructing anangleof 30° with thex-axis, and then finding the coordinates of the corresponding point (0.866, 0.5) on theunit circle. The value of tan 30° is equal to the y-coordinate(0.5) divided by the x-coordinate (0.866). ∴ ...
A circle through the origin can be parameterized by its radius R and the angle Φ, where the circle center is given by xc=RcosΦ, yc=RsinΦ. Such a circle touches the drift circle with center (x w, y w) and radius ρ if, and only if, the squared distance of the circle...
