Answer:
Sin(t) = and
Step-by-step explanation:
The secant function is the reciprocal function of the cosine function. Therefore, given that then, if
then
.
On the other hand, if cos (t) = 1/2 ⇒ t = ±
Then, the sin() =
Answer:
1) -7/4
2) 4/7
3) -1/5
Step-by-step explanation:
1) A parallel line would have the same gradient so:
4y = -7x +3
y =
So a parallel line would have the gradient of .
2) A perpendicular line would have the inverse reciprocal of the gradient so multiplying the 2 gradients would equal -1 so:
Initially Gradient = -7/4
-7/4 x Perpendicular line = -1
Perpendicular line = -1 x 4/-7
Perpendicular line = 4/7
3) Using the same principle, the perpendicular gradient would be -1/5x
