Hello again

I just want to know how to solve this trig equation

The instantaneous power in a stove element is given by the equation

Power = V(0)^2/R sin^2 wtwhere w = 100pi

V(0) = 340 V

t = time (sec)

R = Resistance (ohms)

a) Find the power for a 48 ohm stove element when t = 0.001 seconds

b) Find the max power

c) Find the time at whcih the max power occurs

I'm sure a is a simple 'put a value' in but I get a wierd answer. Please help!
