Let ABCbe an isosceles triangle inscribed ina circle having radius r. Then by figure area of the triangle ABC is `triangle`
Find `(d triangle)/(d theta)` and `(d^2 triangle)/(d theta^2)`.

Let x and y be the length and breadth of the rectangle ABCD in a circle having radius r. Let angleCAB=theta (Ref. Figure). If triangle represent area of the rectangle and r is a constant. Find (d triangle)/(d theta) and (d^2 triangle)/(d theta^2) .

Let x and y be the length and breadth of the rectangle ABCD in a circle having radius r. Let angleCAB=theta (Ref. Figure). If triangle represent area of the rectangle and r is a constant. Write triangle in terms of r and theta .

Hypotenuse of an isosceles triangle is 10cm. Find other two sides of the triangle

Area of triangle BPC is 10 sq.cm. a) Find the area of triangle A B C. b) Find the area of rectangleABCD.

Consider a triangle whose sides are y = x, y = 2x and y = 3x + 4 Find the area of the triangle.

Let x and y be the length and bredth of the rectangle ABCD in a circle having radius r. Let angleCAB=theta (Ref. Figure). If triangle represent area of the rectangle and r is a constant. Hence find the maximum value of triangle .
