Thread: Trigonometric Functions

y= a sin 2pi/T t

What value of T would give the function an amplitude of 5 and a period of 10? It says 10 at the back of book, and I get would that makes the period 10, but how on earth does it affect the amplitude?

Easy question, I know, but I have a test tomorrow and need to get this straightened out. Any help would be appreciated!

Only affects the ampliyude. You are correct to query this.
