Evaluate . 2 tan ^2 45° + cos^2 30° - sin^2 60° + cos 45°/ sec 30�

1.	Evaluate . 2 tan ^2 45° + cos^2 30° - sin^2 60° + cos 45°/ sec 30°+ cosec 30°
Answer» ong>Answer: bhai questions is so simple you have to one PUT the VALUE of SIN, cos, tan, cosec or sec you Get your answer.... and don't be confused..the answer of this questions in NCERT books is different because book answer was give after rationalasing the denominator... ok
