Solve for 0-360 degrees.

tan^2x= 0

Here’s all the points I got for this one.

0 (or 360) and 180 degrees, or 0 and pi. Also, if you are counting all angles included, then the answer is 0, 180, and 360.

Step-by-step explanation:

tan^2x=0

(tan x)(tan x)=0

If either tangent is 0, the whole expression will also be 0, so you can simplify this expression to simply:

tan x=0

Now, tangent is sin/cos, or on a unit circle the y coordinate value divided by the x coordinate value. If the x coordinate value is 0, then the expression will be undefined. Therefore, this expression is only true when y is 0 and x is not. y is 0 at 0 (or 360) degrees and 180 degrees, making those the only two spots where tanx=0. Hope this helps!

x=0°   ,  180°  

Step-by-step explanation:

hello :

tan²x=0 ..tanx=0  all solution is :x=180k   k in Z

for 0-360 degrees :   1) k=0    2 x=0°   so: x=0°

                                  2) k=1   2 x=180°  so: x=180°

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
