- 2 sin A Cos A - Cos A-2 sin A+1=0
- 4(sin^4 30°+cos^4 60°) - (cos^2 45°-sin^2 90°) =2 pls prove this question before tomorrow 2 pm
- show that tan10
- cos18-sin18
- value of 4/cos?A-sin?A+1
- if CosA+secA= 2, find the value of cosA2 and secA2
- Sin A + cosec A = 2
- If cos A + sec A = 2, find value of cos2 A + sec2 A.
- is zero degree is less than and less than 90 degree and zero satisfies 2 sin square theta minus 1 equals to zero find the value of cos theta + cos 2 theta
