Sir, How Can We Determine The Value Of Theta When Representing In Polar Form ?
Asked by Shraddha Acharya | 15th Jun, 2013, 08:53: PM
Okay, so now, if you have
cos(theta) = 1/2, sin(theta) = root(3)/2
Remember you trignometric tables and see for what value of theta is this true i..e cos(theta) = 1/2, sin(theta) = root(3)/2.
You will realize that with cos60 = 1/2 and sin 60 = root(3/2)
and hence, if you will compare it back to the given equations you are trying to solve,
the theta = 60 degree.
