What is sin 7pi/4? I'm currently taking a tirg course and need help
qaws [65]
To ease the understanding, let's write it in degrees and not in Radian:

Formula of conversion: Degree°/180 = Radian/π

Convert 7π/4 in degrees: = (7x180)/4 = 315°

This angle is in the IV th Quadrant of the UNIT circle. So you can write 315° or - 45° .

sin(7π/4) = sin(315°) = sin( - 45°) = - sin(45°) = - (√2)/2

A line contains the points (3,9) and (-1,1) what is the equation of the line?
kirza4 [7]
To find the equation of a line using two given set of points, you must first find slope. To do so, we must use the slope formula:
y2 - y1 / x2 - x1 

In this case:
1 - 9 / -1 - 3 = -8 / -4 
- 8 / -4 = 2 (simplified) 

Now we can use the point-slope formula:
y - y1 = m(x - x1) 

y - 1 = 2(x + 1 )
y - 1 = 2x + 2
y = 2x + 3

In order to make 3x - y = 6 in slope intercept form, we must isolate y.

- y = -3x + 6
Note: y cannot be negative, so we'll multiply both sides by -1 
( -1 ) - y = - 3x + 6 ( -1 ) = y = 3x -6
