d/dx cot(x) = -csc²(x)
d/dx sin(x) = cos(x)
So, if f(x) = 4 cot(x) + 10 sin(x), then
f '(x) = -4 csc²(x) + 10 cos(x)
Answer:
i think probably 80°
Step-by-step explanation:
PQ = RS
2x+3 = 4x-3
x = 3
PTQ = RTS
9y-3x-1 = 5x+7y-5
2y-8x = -4
y-4x = -2
y-4(3) = -2
y-12 = -2
y = -2+12
y = 10
so PTQ = 9y-3x-1
9(10)-3(3)-1
90-9-1
80°
