___________ = tan
2Cos^2 -Cos
Cos A /1-tanA -Sin^2A/CosA -Sin A =Sin A +Cos A
(SecA-CosecA)(1+tanA+CotA)=tanA SecA -CotA CosecA
tan^2/tan^2 -1 +Cosec^2 / SEc^2 -Cosec^2 = 1/Sin^2 - Cos^2
Eliminate in the equation
Cot +Cos =m , Cot - Cos =n
-2Sin -Cos /tan^2 -1 +Cosec^2 / SEc^2 -Cosec^2 = 1/Sin^2 - Cos^2 in the equation +Cos =m , Cot - Cos =nAsked by tejvarun | 15th Jun, 2017, 06:03: PM

- sec²a.cosec²a = tan²a + cot²a+ 2
- (sin A+ cos A) (sec A+ cosec A) = 2+sec A.cosec A
- tan2-sin2=tan2.sin2
- cot2 A - cos2 A = cot2 A × cos2 A
- prove that 3(sinA-cosA)^⁴+6(sinA+cosA)^²+(sin^⁶A+cos^⁶A)=14
- Prove that √1+cosø/1 -cosø + √1-cosø/1+cosø = 2cosecø
- tan^2 a - sin^2 a =
- 1st question please solve it !
- prove that: sin^3/cosA + sinAcosA = tanA
