What is the trigonometric value to sin(0)?
Using the unit circle, you come to the conclusion that sin(0) is zero. this can also be solved by partitioning the quadrant into triangles and using the special triangle rules.
solve the quadratic formula using the values a=2 b=7 and c=1
plug the numbers into the equation that can be remembered by the saying " a negative boy was undecisive whether to go to a radical party of be squared and miss out on four awesome chicks which would be over at two am" once the numbers are plugged into the equation you get -7 plus or minus the square root of (49-8) all over 4 which simplifies to -7 plus or minus the square root of (41) all over 4
Solve the equation x+63=3x+1
subtract the x to the right side and subtract the one to the left side so you get similar variables on each side together. Collect like terms and then divide by 2.
