Answer 1

Answer:

This only has answer 1. these proofs are really long, so hard to fit them all in one answer.

Step-by-step explanation:

$cos^2A+sin^2A=1$ : Will be used very often so just remember this equality.

1. Multiply $(1+SinA)*\frac{CosA}{1-SinA} +\frac{CosA}{1+SinA} *(1-SinA)=2secA$

When we factor out the terms, we are left with:

• $\frac{CosA}{1-Sin^2A} +\frac{CosA}{1-Sin^2A} =2secA$

We then use the rule above and convert it to $cos^2A$:

• $\frac{1}{CosA} +\frac{1}{CosA} =2secA$
• $2secA=2secA$
