Question

3 cos 90° + sin 45° + tan 60°

Answer 1

Answer:

$3 \cos(90) + \sin(45) + \tan(60) \\ = 3 \times 0 + \frac{1}{ \sqrt{2} } + \sqrt{3} \\ = \frac{1}{ \sqrt{2} } + \sqrt{3} \\ = \frac{1 + \sqrt{6} }{ \sqrt{2} }$

Answer 2

Answer:

Step-by-step explanation:

sin45=1/sqrt(2)

tan60=sqrt(3)

cos90=0

3*0+1/sqrt(2)+sqrt(3)=sqrt(3)+1/sqrt(2)
