Inverse is used to find the value of an angle. The inverse of a trigonometric function gives you the angle instead of the ratio. Commonly, these are denoted with the prefix "arc-". So, the inverse of the tan function is the arctan function.
The reciprocal of a trigonometric function is simply its algebraic reciprocal--that is, 1 over the function.
Answer:
I cannot see it well
Step-by-step explanation:
Solve for n.
0.2(n - 6) = 2.8
Distribute
0.2*n - 0.2*6 = 2.8
0.2n - 1.2 = 2.8
Now inverse operation should be applied
0.2n - 1.2 = 2.8
+ 1.2 +1.2
2.8 + 1.2 = 4
0.2n = 4
0.2n/0.2 = 4/0.2
n = 20
Answer: 20
