1. I recently got a new calculator for A level fmaths and i keep getting the wrong answers for trig values. How can i fix this?
2. either you need to get out of radians or get into radians
3. it's probably in radians mode

5. Cos(60) (degrees) is 1/2. Cos(60) (radians) is -0.952. Need to change the setup of your calculator so it's using degrees rather than radians
