Find the exact value of each trigonometric function:1) cot 135 degrees
2) tan -30 degrees
3) cot (-pi)

Show your work.

This is from trigonometry or Algebra 2.
Please don't answer if you don't know it.

Answers

Answer 1

Answer: cot 135 is the same a 1/tan 135, which is equal to 1/-1, so cot 135 is -1

tan -30 is the same as tan 330, which is - $√(3 )$ / 3

cot -π = 1 / tan π, which is 1 / 0, and you can't divide by 0, so cot -π is undefined

The formula for the height of a ball as a function of time is given by the equation h = -16t^2 + vt + h, where h is the height of a ball in feet, v is the initial velocity of the ball in feet per second, h is the initial height of the ball in feet, and t is the time in seconds after the ball was thrown.If a ball is thrown from an initial height of 5 feet at an initial velocity of 20 feet per second, what is its height after 1 second?

Answers

It's really poor form to use 'h' to mean two different things in two different
places in the same formula. Fortunately, we know what you mean.

H = h + vt - 16t²

You have said that ...
initial height = 5 feet
initial velocity = 20 feet per second, no direction given
time = 1 second

Since you gave us the magnitude of the initial velocity but not its direction,
there are a huge number of possibilities. I'll focus only on two of them:
20 feet per second straight down, and 20 feet per second straight up.

Initial velocity is downward:
H = (5) + (-20) (1) - 16 (1)²
H = 5 - 20 - 16 = 5 - 36 = 31 feet underground after 1 second

Initial velocity is upward:
H = (5) + (20) (1) - 16 (1)²
H = 5 + 20 - 16 = 25 - 16 = 9 feet above ground after 1 second

determine whether the given first-order differential equation is linear in the indicated dependent variable by matching it with the differential equation given in (7) in section 1.1, a1(x) dy dx a0(x)y

Answers

The given first-order differential equation is linear in the indicated dependent variable because it matches the standard form of a linear first-order differential equation, a1(x) dy/dx + a0(x)y = f(x).

First, let us review what a linear first-order differential equation is. Ais a differential equation that can be written in the form:

a1(x) dy/dx + a0(x)y = f(x)

Now, let us compare the given differential equation to the standard form of a linear first-order differential equation. The given differential equation is:

a1(x) dy/dx + a0(x)y

As we can see, the given differential equation matches the standard form of a linear first-order differential equation. Therefore, we can conclude that the given differential equation is linear in the indicated dependent variable.

In conclusion, the given first-order differential equation is linear in the indicated dependent variable because it matches the standard form of a linear first-order differential equation, a1(x) dy/dx + a0(x)y = f(x).
