If we take the square of x and square of y and then subtract them:
(csc t)²-(cot t)²=1 ( this eq. gets from basic identity
x²-y²=1......a 1+cot²x=csc²x)
equation 'a' represent the equation of hyperbola which is (x²/a²)-(y²/b²) =1 with given conditions( a=1,b=1)
So, option D is correct
Answer: divide the numerator(top) by the denominator (bottom) then multiply the answer by 100. Hope this helps!
61:1 or 61 miles per hour! This is because 183 divided by 3 is 61!
