Look at sin and cos graphs. Start from x=0 and go right. When does cos value become negative? When does it come close to -1? What about sin value?Hi just wondering if anyone would be able to help me solve this question
I have tried looking through some stuff about trig functions but cannot find how to solve the question
Any sort of help would be greatly appreciated
Thanks
