Q4 of 268 Page 4

Evaluate the following :
tan30°.sec45° + tan60°.sin30°

We know that

sec (45^o) = √2

tan (60^o) = √3

Now putting the values, we get

Evaluate the following :

2sin²30°.tan60° – 3cos²60°.sec²30°

Evaluate the following :

tan60° . cosec²45° + sec²60°.tan45°

Evaluate the following :

cos30°.cos45° – sin30°.sin45°

Evaluate the following :

Evaluate the following :tan30°.sec45° + tan60°.sin30°
