1) Thus point (3,4) is represented as (5,53
) in polar format.
2) Polar form is![r=tan(\theta )sec(\theta)](/tpl/images/0188/7556/fda40.png)
Step-by-step explanation:
Any point (x,y) can be represented in polar format (r,θ) as
Using the above formula
The point (3,4) is represented in polar format as
Thus point (3,4) is represented as (5,53
)
2)
The given curve is![y=x^{2}](/tpl/images/0188/7556/94ca9.png)
to convert it to polar form put
Thus the curve becomes

Given:
RUTS is a rectangle.
To prove:
∠USR ≅ ∠SUT
Statements Reasons
1. RUTS is a rectangle 1. Given
2. RU = ST, UT = RS 2. By the definition of a rectangle
3. ∠STU = ∠SRU = 90° 3. Definition of a rectangle
4. ΔURS ≅ ΔSTU 4. By the LL theorem of congruence
5. ∠USR ≅ ∠SUT 5. CPCTC
