1. Find the value of
spin [16.1K]

9514 1404 393

Answer:

  1. -√5
  2. 3/5
  3. -4/5

Step-by-step explanation:

The relevant relations are ...

  sec = ±√(tan² +1)

  cos = 1/sec

  csc = 1/sin = ±1/√(1 -cos²)

Sine and Cosecant are positive in quadrants I and II. Cosine and Secant are positive in quadrants I and IV.

__

1. sec(θ) = -√((-2)² +1) = -√5

2. cos(θ) = 1/sec(θ) = 1/(5/3) = 3/5

3. csc(θ) = -1/√(1 -(-3/5)²) = -√(16/25) = -4/5

Solve the following for the x and y values. X being 0 when solving for Y, and vice versa.
Aleonysh [2.5K]
It states your "X" will be zero when solving for "Y". So when solving for "Y" your equation would be; 0+y=4 Then you solve. Y=4 Then you do the same with the "X": X+0=4. Then you solve. X=4 It would end up being (4(x),4(y) ) Then do the same for the next problem.
