Start by converting to like terms, so convert 1/2 to 2/4.

Next, look at the problem. You are adding a negative, which is the same as subtracting, so your new problem looks like this: 2/4 - 3/4.

If you take 3/4 from 2/4, you are left with -1/4. This is your final answer!

The person who can prove this all question will get the brailiest award
MrRa [10]

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
