On your calculator, input the value of either your sine or your cosine. Then press "inv." This should give you the angle associated with that value. The angle associated with sin 0.923 or cos 0.384 is 67.38 degrees. Add 90 to the angle you just calculated, and subtract the sum from 18...

How to calculate the sine of an angle without using a calculator? Sine Ratio: The sine of an angle is given by the quotient between the opposite side and the hypotenuse of a right triangle. This quotient, as well as other types of quotients, are known as trigonometric ratios. These trig...
I have a toy calculator I've been tasked to create for a class project. That's great - I have most of the normal calculator stuff done (order of operations, variables, precision settings, predefined functions). The issue is that, since I'm using rational arithmetic, there...
The measure of the central angle of a regular hexagon is 60 degrees. A hexagon layout calculator can be a helpful tool for basic measurement questions about the hexagon. Designers as well as carpenters often use them to help layout a perfect hexagon pattern in the designing and building of ti...
euler helps you to calculate in an easy way with the complex impedance, by using the e e power. at the end of the calculation you can separate the complex power of e e into its real and imaginary parts. these agree with your resistance and reactive impedance resp. | z | = r...
Multiply each side of the equation by 6 to isolate the sine measurement of the unknown angle. This gives you: 0.75 = sin(B) Find the inverse sine or arcsine of the unknown angle, using your calculator or a table. In this case, the inverse sine of 0.75 is approximately 48.6 degrees. ...
To find the cosine of an angle on a calculator, you can use the "cos" button, usually located near the top of the calculator. First, enter the value of the angle in degrees or radians, depending on the mode of your calculator. Then, press the "cos" button to calculate the cosine...
Trig Functions:When you're working with angles, keep in mind many calculators let you select whether to express the answerin degrees or radians. Then, you need to determine whether you enter the angle (check the units) and then sin, cos, tan, etc., or whether you press the sin, cos,...
