Question

Help here please:

Answer 1

Can you show me number one, and I will solve the other two

Answer 2

get your calculator and enter:
y1 = sin(x)^2 + cos(x)^2
y2 = 1

Answer 3

then graph. make sure your in radian mode with trig view.

Answer 4

i forgot... you have a texas instruments (TI-xx) calculator?

Answer 5

yes, the texas t1-83

Answer 6

i guess with this exercises you're just verifying these identities... each pair should produce the same graph...
the second one is a bit peculiar (as far as the graph is concerned) though...

Answer 7

for the seond one, when I graph it, I graph it as 1/sin theta right?

Answer 8

fpr csc

Answer 9

1/sin theta²

Answer 10

yes. also, make y2 a "fat" graph. do you know what I mean?

Answer 11

fat graph? what does that mean?

Answer 12

move the cursor all the way to the left using the left arrow key. once you get there press enter once.

Answer 13

Ok. so for the first problem, the graph is a straight line right on 1

Answer 14

yes, the fat graph is on the skinny graph..

Answer 15

ok. That makes sense. Thank you @dpainc!

Answer 16

what i meant about being peculiar about the second one is that for y1 function, you'll have restricted domain but for y2 it's just a continuous horizontal line.

Answer 17

oh, yw... :)
