Evaluate \int_C y^3 dx - x^3 dy where C is the positively oriented circle of radius 2 centered at the origin. Let f(x,y) = x^2 + y^2 and let C be the arc of the circle between the points (1,1) and (-...
Find the value ofsin[arccos(−12)] View Solution Find the degree measure of the angle subtended at the centre of a circle of radius 100 cm by an arc of length 22 cm (useπ=227). View Solution Find the area of the sector and length of the arc subtended by a central angle of2π...
The degree of a curve is an important measurement used in land surveying. You can determine the degree of any curve by first finding the circumference of a circle. Step 1 Multiply the radius of any circle by π, a numerical constant that begins with 3.142, and represents the relationship be...
