Answer:
i just took the test, so its b. 84
i dont know hwy
Just solve the square roots and compare all four to see which one is the normalest
Answer:
Step-by-step explanation:
sin(2x) = 2 sin(x) cos(x) cos(2x) = cos2(x) – sin2(x) = 1 – 2 sin2(x) = 2 cos2(x) – 1. Now I am not sure if this is right but I remember another similar formula. Here is the correct formula cot x = cos x / sin x
2 ) ( sin² x + cos² x ) / cos x = sec x
1/cos x = sec x
sec x = sec x
cos² x + sin² x = 1
A: parallel
B: perpendicular
C: neither
D: perpendicular
E: parallel
Explanation: Parallel lines have the same slope. Perpendicular lines have inverted and converted slopes. Neither has neither.
