Value of 1 + cos2 theta |
|
Answer» Answer: (1-cos2theta) = sin SQ THETA + cos sq theta - (cos. sq theta-sin sq theta) Since cos2theta = cos aq theta - sin sq theta After simplifying the equation (1-cos2 theta) = 2sin sq theta (1+cos2 theta) = sin sq theta + cos sq theta +( cos sq theta -sin sq theta) After simplification (1+cos2theta) = 2cos sq theta Now (1-cos2theta)/(1+cos2theta) = tan sq theta Step-by-step explanation: |
