Ah, I wasn't told I could convert radians to degrees. Thank you.Samy_A said:

That's what the 'RAD'/'DEG' button in the upper left hand calculator is for, to allow you to select the units of angular measure.Alanay said:Ah, I wasn't told I could convert radians to degrees. Thank you.
No, I did poorly in my Math exams. Now I am going to be studying science and engineering which is very ambitious if you think about my past with mathematics. But now I'm 18 it isn't very difficult to grasp different concepts so I'm learning at a much faster rate. My only problem is not being distracted. Thanks for notifying me of the option on the calculator, I never noticed it before.SteamKing said:
To calculate inverse trig functions using a calculator, you will need to use the inverse trig function keys (usually labeled as "sin-1", "cos-1", or "tan-1"). Press the appropriate key, then enter the value you want to find the inverse of and press "enter". The calculator will display the inverse trig function value.
To calculate inverse trig functions without a calculator, you will need to use a trigonometric table or a trigonometric identity. For example, to find the inverse sine of a value, you can use the identity sin-1x = cos-1√(1-x2). You can also use a calculator or a computer program to generate a table of inverse trig function values.
The main difference between inverse trig functions and regular trig functions is the input and output. Regular trig functions take an angle as input and output a ratio of sides in a right triangle. Inverse trig functions take a ratio of sides as input and output an angle in radians or degrees.
You should use inverse trig functions when you know the value of a ratio of sides in a right triangle and want to find the angle that corresponds to that ratio. Inverse trig functions are also used in solving real-world problems involving angles and distances.
No, inverse trig functions can only be used to solve right triangles. To solve an oblique triangle, you will need to use the law of sines or the law of cosines. Inverse trig functions are only applicable when one angle of a triangle is 90 degrees.
