Isnt the sin2theta=sintheta*cosTheta?
You are given cosTheta=1/3, so use
sin^2 theta + cos^2 theta=1 to find sinTheta.
Can someone help me with this problem please? Thank-you to those who helped me with the previous ones and I understand those. But, I tried this one and I don't understand it.
Use the information given about the angle Ɵ to find the exact value of:
sin 2Ɵ.
1) secƟ= 3, SinƟ > 0
