Which expressions are equivalent to −tan⁡ θ?

Mathematics

zzz [600]3 years ago

Answer:

−1/cotθ

1/cot(−θ)

tan(−θ)

Step-by-step explanation:

The tangent function is a the ratio for an angle defined as opposite / adjacent.  A negative applied to −tan⁡ θ will give the opposite value. This is also true for the function when taken on a negative angle. tan(−θ) = −tan⁡ θ. This identity is also true for sin, sec, and cot. Recall that cotangent is the reciprocal of tangent and is defined as the ratio adjacent / opposite. Taking the reciprocal of cotangent will be the same as tangent. Using this information the following are equivalent:

1/cotθ

−1/cotθ  ----> The reciprocal of Cot is Tan

1/cot(−θ) ----> The reciprocal of Cot is Tan and cot(−θ) = −cot⁡ θ.

−1/cot(−θ)

tan θ

tan(−θ)----> tan(−θ) = −tan⁡ θ

Solve for x <br><br> log(7x+1) = log(x-2) + 1
myrzilka [38]
Log(7x+1) - log(x-2) =1

log[(7x+1) / (x-2)] =1 or log[(7x+1) / (x-2)] =log10 (log10=1)

it means (7x+1) / (x-2) =10

Solving ===> x=7

Lance went to see the Colosseum.

Height of the outer wall of the Colosseum = 48 meters

Unit Conversion formula:

1 meter = 3.28 feet

To find:

Height of the outer wall of the Colosseum in feet.

Solution:

It is simple problem for the conversion of unit where we already know the value in one unit and the conversion formula as well.

We have to simply find how much 48 meters will be when converted in feet.

1 meter = 3.28 feet

48 meter = 48 \times 3.28 = <em>157.44 feet</em>
