What is the value of cosθ given that (−2, −3) is a point on the terminal side of θ ?
snow_tiger [21]

Answer:

-0.555

Step-by-step explanation:

The terminal point of the vector in this problem is

(-2,-3)

So, it is in the 3rd quadrant.

We want to find the angle \theta that gives the direction of this vector.

We can write the components of the vector along the x- and y- direction as:

v_x = -2\\v_y = -3

The tangent of the angle will be equal to the ratio between the y-component and the x-component, so:

tan \theta = \frac{v_y}{v_x}=\frac{-3}{-2}=1.5\\\theta=tan^{-1}(1.5)=56.3^{\circ}

However, since we are in the 3rd quadrant, the actual angle is:

\theta=180^{\circ} + 56.3^{\circ} = 236.3^{\circ}

So now we can find the cosine of the angle, which will be negative:

cos \theta = cos(236.3^{\circ})=-0.555

Here’s the answer and each step I took to solve it. With the example I made on the side just continue to repeat that for each one to get the answers. You just replace that one number for the X to take the place for the next X value as you go down the table solving them.
