On the unit circle, where 0 less-than pi, when is tangent theta undefined?

Mathematics
1 answer:
topjm [15]3 years ago
4 0

Answer:

Step-by-step explanation:

Recall that on the unit circle, each point is represented as (\cos(\theta), \sin(\theta)) where 0\leq \theta \leq 2\pi. In this case, we are asked to take a loot at the interval 0 \leq \theta \leq \pi.

We will use the definition of tangent to solve the problem. REcall that

\tan(\theta) = \frac{\sin(\theta)}{\cos(\theta)}

So, in this case, tangent is undefined whenever the denominator is zero. That is, when \cos(\theta)=0. Checking the unit circle with the interval 0 \leq \theta \leq \pi, this restriction corresponds to the upper half of the unit circle. In this case, the x component of each point is cosine. We are interested at the points where \cos(\theta)=0.

. This happens only at the point (0,1), which is associated with the value of \theta = \frac{\pi}{2}

A man starts at a point A and walks 18 feet north. He then turns and walks due east at 18 feet per second. If a searchlight plac

Answer:

1/10 per sec

Step-by-step explanation:

When he's walked x feet in the eastward direction, the angle Θ that the search light makes has tangent

tanΘ = x/18

Taking the derivative with respect to time

sec²Θ dΘ/dt = 1/18 dx/dt.

He's walking at a rate of 18 ft/sec, so dx/dt = 18.

After 3seconds,

Speed = distance/time

18ft/sec =distance/3secs

x = 18 ft/sec (3 sec)

= 54ft. At this moment

tanΘ = 54/18

= 3

sec²Θ = 1 + tan²Θ

1 + 3² = 1+9

= 10

So at this moment

10 dΘ/dt = (1/18ft) 18 ft/sec = 1

10dΘ/dt = 1

dΘ/dt = 1/10 per sec

Answer: x=2.4

Step-by-step explanation: I believe that you plug what y equals into the x value so both variable are x and you can solve for x
