Answer» 1-cos(2A) + sin (2A)___________________1 + cos(2A) + sin(2A) 1 - ( 1 - 2sin^2(A)) + 2sin A cos A_____________________________1 + 2cos^2(A) - 1 + 2sin A cos A 2sin^2(A) + 2sin A cos A______________________2cos^2(A) + 2sin A cos A 2sin A( sin A + cos A)___________________2cos A(cos A + sin A) = sin A / cos A = tan A 3.tanA is the right answer

The value of1-cos2A+sin2A1+COS2A+sin2A=The value of 1.6082a+sin2A =Options :1 sinA2. COSA3. tanA4. cotA

Answer»

1-cos(2A) + sin (2A)___________________1 + cos(2A) + sin(2A)

1 - ( 1 - 2sin^2(A)) + 2sin A cos A_____________________________1 + 2cos^2(A) - 1 + 2sin A cos A

2sin^2(A) + 2sin A cos A______________________2cos^2(A) + 2sin A cos A

2sin A( sin A + cos A)___________________2cos A(cos A + sin A)

= sin A / cos A

= tan A

3.tanA is the right answer
