Objective: I know how to use the calculator to find the inverse of the trigonometric functions: sin, cos, tan.
If we know the size of an angle, we can find the sin, cos and tan of the angle by using a scientific calculator. We can also use a calculator to find the inverse or reverse of this. If we know the sin, cos or tan of an angle, we can find the size of the angle.
Refer to the lesson on how to use the calculator to evaluate the inverse of trigonometric functions for more information and examples.
We hope that the free math worksheets have been helpful. We encourage parents and teachers to select the topics according to the needs of the child. For more difficult questions, the child may be encouraged to work out the problem on a piece of paper before entering the solution. We hope that the kids will also love the fun stuff and puzzles.
