Question about Texas Instruments TI-15 Explorer Calculator
Can you figure Sine, cosign and tangent on the TI-15?
Not directly. The calculator does not have the trig functions built in. You could do it the same way people did it before pocket calculators.

Alot of people seem to be having this problem. Angles can be measured
in two units, degrees and radians. Your calculator is currently doing
everything in terms of radians. I have an 84 but I'm sure the 83 is
similar, go under MODE and look for Degrees and Radians and make sure
you choose degrees. if you have to convert, 360[degrees] = 2* pi
(easy to remember, 360deg in a circle, 2pi radians in a circle)
