If ( 2 sin 2 theta cos 2 theta 2 ) then find the value of ( theta ) - Given:( 2 sin ^{2} theta-cos ^{2} theta=2 )To do:We have to find the value of ( theta ).Solution: $2 sin ^{2} theta-cos ^{2} theta=2$$Rightarrow 2 sin ^{2} theta-(1-sin ^{...
Therefore, tan formulas are $\tan \theta = \dfrac{{\sin \theta }}{{\cos \theta }}$ and $\tan \theta = \dfrac{{BC}}{{AB}}$ . 90-Degrees Angle An angle of $90$ degrees is created when two straight lines cross perpendicularly. In other words, the angle between two radii of ...
