Question

Tan 45 * cos 45 + tan 30 * tan square 60​

Answer 1

Answer:

$\frac{1}{\sqrt{2}}+\frac{3}{\sqrt{3}}$  , by the way, the simplified is $2.439157589$

Step-by-step explanation:

I included a chart so next time you don't need to worry

• tan( 45 degrees) = 1
• cos( 45 degrees) = $\frac{1}{\sqrt{2}}$  

• tan( 30 degrees) = $\frac{1}{\sqrt{3}}$

• tan squared (60 degrees) is the same as saying square the answer of tan (60 degrees). So tan( 60 degrees) = $\sqrt{3}$ , so square

Answer 2

Answer:

Regroup Terms: cos 45 tan 45x + tan​^2​​ tan 30x, 60
