These are a few questions which are really tricky and tough:
1. If 8x = cosec A and 8/x = cot A, find the value of 4(x-1/x^2).
2. Prove that (cos theta + sin theta)^2 = (√2 cos theta)^2.
3. cos A/1-tan A - sin^2 A sec A cosec A/cosec A- sec A = cosec A+ sec A/sec A cosec A
4. (1+ sin A/ cos A × sin B/ cos B)^2 + (sin A/ cos A - sin B/ cos B)^2 = 1/ cos^2 A cos^2 B.
4. If tan theta + 1/tan theta = 2, find the value of tan^2 theta+ 1/ tan^2 theta.
5. If sin theta+ cos theta/ sin theta - cos theta= 5/3, find the value of 7 tan theta +2/2 tan theta+7.
/ is ÷ and ^2 is square.
