A) Verify the following Identities :
i) [(Sin 2theta)/ (sin theta )- ( cos 2theta/ cos theta )] = sec theta
ii) cos2x = (cot^2 x-1 )/ (cot^2 x-1 )
ììì) Use logarithms and the law of tangents to solve the triangle
ABC, given that a= 21.46 ft, b= 46.28 ft, and C = 32° 28' 30"
Oblique Triangles and Identities are investigated.
