You need to find midpoint of the diameter. To find x coordinate you take (x1 + x2)/2 = (1+6)/2 = 7/2 And same thing for y. ( y1 + y2)/2 = (3+6)/2 = 9/2.
Answer: 36
Step-by-step explanation:
-3 to the power of -2 is 9
2 to the power of 1 is 4
when you multiply that u get 36
Tan(a/2) = sin a / (1 + cos a)
tan(45/2) = sin(45) / (1 + cos(45)) = (1/√2) / (1 + 1/√2) = (1/√2) / (√2 + 1)/√2 = 1/(√2 + 1) = (√2 - 1)
T -1,-1 ect ect hope helps
