question_answer 1)

Find the area in the first quadrant enclosed by x-axis, line and the circle x2 + y2 = 4.  

Answer:

Given curves area x-axis.       x =       x2 + y2 = 43       For (1),             (2), x2 + y2 = 4 is a circle with C = (0, 0) and r = 2             The intersection points are                         (By solving (1) and (2))       Required area = shaded area
