Using a Calculator to Find Values If you have a scientific calculator, you can determine the value of any trig function for any angle. Here we will focus on using a TI graphing calculator to find values.... So if you can find an angle #alpha# for which you know some trig values that is close to #theta#, then you can use these to construct a good approximation for #cos(theta)# For your example, I am not sure whether #5.22# is in radians or degrees.

21/10/2008Â Â· Best Answer: prior to calculators, they had tables. There is not a good way to find the EXACT value. We can only approximate. If you have Calculus, then you can change it into radians and then do a series expansion. If the value is in radians ,then sin x apprx equal to x - x^3 / 3 + x^5 / 5 - â€¦...1.
