1. Find the perimeter of the square then the circumference of the circle then subtract the circle from the square.
Area of square=length of side squared=9.8^2=96.04.
Area of circle=(pi*radius)^2=((22/7)*(9.8/2))^2

2. Area of circle=pi*r squared
38.5=((22/7)*r)^2
Solve for r
Square root of 38.5/(22/7))=r
calculate area using above formula

Sec theta - Csc theta / (csc theta)(sec theta)

Sophie [7]

Answer:

sin(x)-cos(x)

Step-by-step explanation:

$\frac{\frac{1}{cos(x)} - \frac{1}{sin(x)} }{\frac{1}{sin(x)} * \frac{1}{cos(x)} }$

Simplify the denominator:

$\frac{\frac{1}{cos(x)} - \frac{1}{sin(x)} }{\frac{1}{cos(x)sin(x)} }$

Simplify the numerator:

$\frac{{\frac{2(sin(x)-cos(x))}{sin(2x)} } }{\frac{1}{sin(x)} * \frac{1}{cos(x)} }$

Divide the fractions: <u>(a/b)/(c/d) = (a * d)/(b * c)</u>:

$\frac{(-cos(x)+sin(x))*2cos(x)sin(x)}{sin(2x)}$

Use the identity: <u>2cos(x)sin(x) = sin(2x):</u>

$\frac{sin(2x)(-cos(x)+sin(x))}{sin(2x)}$

Cancel out the common factor (sin(2x)):

-cos(x) + sin(x)

Simplify:

sin(x) - cos(x)
