Question

What is the graph of the function f(t)= 5 sin 3t

Answer 1

The answer is B.

Answer 2

in the graph

Explanation:

the function g(t)= sin t is a periodic function with amplitude a0= 1 and period T0=2
`\pi`

For our case, the 5 that multiplies g (t) increases the amplitude so that a = 5 * 1 = 5 and the 3 that multiplies the variable increases the period being T = 2
`\pi`*1/3 = 2
`\pi`/3
