Thread: Trigonometry help needed! Graphing and interpretation

Trigonometry URGENT help needed!!! 5 Questions ((?

g(x) = sin2x
f(x) = cos(x-60)
x element [-180; 180]
I have used 30 degree intervals

a) What is the period of f?????

b) Determine f(x0 - g(x) if x = 0

c) Use the graph to determine the value(s) if x for which f(x) < 0

d) For which values of x is f(x).g(x)>0 if x element[-180; 0]

e) Write down the equation of h if h(x) = f(x-30)

These are the 5 questions that are bothering me in my entire maths assignment, solving all / as much as you can is appreciated Please solve them as they are important

Hey TechWizNo.

Please show us any attempts and what is going on in your head.

I'll start you off with a hint for Q1.

Hint: The period of a function is a where f(t + a) = f(t) for all values of t. What is the value of a?
