Can anyone help me with my math homework! My teacher didn't even discuss it! I would appreciate it! Thank you!
Hatshy [7]
Please, in the future, post just one problem at a time.

Looking at Problem #1:  The line intersects the y-axis at (0,-3) and intersects the x-axis at (1,-1).  At least, this is what I see; your graph is small.
                                                                           -3-[-1]
The slope of that line is then  m = rise / run = ------------ = +2.
                                                                            0 - 1
                                       [change in y]
Slope = m = rise / run = --------------------
                                        [change in x]

1-sin^2x/sinx-cscx <br><br>How do I solve this problem? I keep getting the wrong answer.
Annette [7]

Answer:

-sinx

Step-by-step explanation:

a trig identity that is crucial to solving this problem is: sin^2 + cos^2 = 1

with knowing that, you can manipulate that and turn it into 1 - sin^2x = cos^x

so 1-sin^2x/sinx - cscx becomes cos^2x/sinx - cscx

it is also important to know that cscx is the same thing as 1/sinx

knowing this information, cscx can be replaced with 1/sinx

(cos^2x)/(sinx - 1/sinx)

now sinx and 1/sinx do not have the same denominator, so we need to multiply top and bottom of sinx by sinx; it becomes....

cos^2x

---------------------

(sin^2x - 1)/sinx

notice how in the denominator it has sin^2x-1 which is equal to -cos^2x

so now it becomes:

cos^2x

--------------

-cos^2x/sinx

because we have a fraction over a fraction, we need to flip it

cos^2x          sinx

---------- * ----------------

1                  -  cos^2x

because the cos^2x can cancel out, it becomes 1

now the answer is -sinx
