Question

Evaluate; tan^2 60 - sin^2 45.​

Answer 1

Answer:

tan^2 60 - sin^2 45

= (√3)^2- (1/√2)^2

= 3-1/2

= 6-1/2

= 5/2

Answer 2

Answer:

$\frac{5}{2}$

Step-by-step explanation:

The exact value of tan(60) is sqrt(3), and sin(45) is 1/sqrt(2)

tan^2 (60) - sin^2 (45)

$=(\sqrt{3})^2-(\frac{1}{\sqrt{2}} )^2\\=3-\frac{1}{2}\\ = \frac{5}{2}$
