If the region in the first quadrant bounded by the graph of y=cosx and the interval[0,pi/2] is bisected by the line x=c, guess c.

  • Calculus -

    You need the
    integral [cosx]dx from0 to c = integral [cosx]dx from c to π/2
    sinc = sin π/2 - sinc
    2sinc = sin π/2
    sinc = 1/2
    c = π/6

    Why are you supposed to "guess" ?

    thats what the question said
