Explain the difference between using the tangent ratio to solve for a missing angle in a right triangle versus using the cotange

Lena [83]

Answer:

While determining the angle $\theta$ with the tangent ratio or cotangent ratio uses the same sides lengths but the ratios are inverse of each other.

Step-by-step explanation:

See the diagram attached.

Let us assume a right triangle Δ ABC with ∠ B = 90°. Now, assume that the angle ∠ CAB = $\theta$ and the sides AB, BC, CA are 3, 4, 5 units respectively.

The tangent ratio of an angle $\theta$ is given by

$\tan \theta = \frac{BC}{AB} = \frac{4}{3}$

Again, the cotangent ratio of angle $\theta$ is given by

$\cot \theta = \frac{AB}{BC} = \frac{3}{4}$

Therefore, in both the cases of tangent ratio and cotangent ratio are inverse of each other and while determining the angle $\theta$ with the tangent ratio or cotangent ratio uses the same sides lengths but the ratios are inverse of each other. (Answer)

f of x equals the quantity x minus one times the quantity x plus two times the quantity x plus four all divided by the quantity

Alik [6]

$f(x)=\frac{(x-1)(x+2)(x+4)}{(x+1)(x-2)(x-4)}$

The denominator of a fraction can't be equal to 0.
$(x+1)(x-2)(x-4) \not= 0 \\
x+1 \not=0 \ \land \ x-2 \not= 0 \ \land \ x-4 \not= 0 \\
x \not= -1 \ \land \ x \not = 2 \ \land \ x \not= 4$

The function is undefined at x=-1, x=2, x=4, because for these values the denominator of the function would equal 0, and it's impossible to divide by 0.

Edward is correct.
