Question

5 sin2 30° + cos2 45°- 4tan2 30°
___________________________
2sin 30° cos 30° + tan 45°

Evaluate each of the following
​

Answer 1

Answer:

5 *2 sin30° cos30° + cos²45° - sin²45° - 4 ( sin2 30°/ cos2 30° )

______________________________________

2sin30° cos30° + tan45°

=>

5 * 2 * 1/2 * √3/2 + ( 1/√2)² - (1/√2)² - 4 ( 2 * √3/4 )*2

______________________________________

2*√3/4 + 1

=>

5√3/2 - 4√3

___________

√3/2 + 1

=>

5√3 - 8√3 /2

___________

√3+1/2

=>
