Answer:

x^2+y^2=(x^2+y^2-2y)^2

Step-by-step explanation:

Here we are given that

r=1+2sin

we know that the polar cordinates are represented as

x=rsin

y=rcos

Also squaring both and adding them gives you ,

Hence

also r=1+2sin

1+2sin =

Also ,

r = r=1+2sin

also sin =

Hence replacing sin we get

Answer:

Isosceles Right Triangle

Step-by-step explanation:

We look at the sides first. Two sides are equal, which means that the triangle is isosceles (equilateral means three equal sides, and scalene means no sides equal). Then we look at the only angle indicated, which is the right angle. Thus, we come to the conclusion that the triangle is an Isosceles Right Triangle.

Given tan θ = 2 and sin θ &lt; 0. Find cos(θ +pi/4)
Lera25 [3.4K]

Answer:

√10 / 10

Step-by-step explanation:

tan θ > 0 and sin θ < 0, so θ is in quadrant III.  That means cos θ < 0.

cos(θ + π/4)

Use angle sum formula.

cos θ cos(π/4) − sin θ sin(π/4)

½√2 cos θ − ½√2 sin θ

Factor.

½√2 cos θ (1 − tan θ)

½√2 cos θ (1 − 2)

-½√2 cos θ

Write in terms of secant.

-½√2 / sec θ

Use Pythagorean identity (remember that cos θ < 0).

-½√2 / -√(1 + tan²θ)

-½√2 / -√(1 + 2²)

½√2 / √5

√10 / 10
