Question

Please help!!! I don't get this!!! 100 POINTS!!!!

Answer 1

Hey there! The answer to this question should be the letter B.0<a2 <a1

Its giving a line to sin(x) and to the solid line is giving cos(x), so in my perspective the sin(x) has the biggest amount  than cos(x). So you will get  a1 > a2, which is the choice B.

Answer 2

Recognizing that the dotted line is sin(x) and solid line is cos(x), it's clear to see that the sin(x) has a larger amplitude than cos(x). So, we get a1 > a2.

Only B and E satisfies the above. But E is clearly incorrect since amplitude cannot be less than 0.

Therefore, B would be the correct choice.
