    Mathematics: Post your doubts here!

    :eek: Use the same method you applied for first point. Plug in the value of x If you dont remember the absolute value use your calculator. Pi is 180. So 5(180)/6 is 150 cos 150 is negative. And negative*negative gives out positive, And positive values are always minimum

    Look. You got the right answers and yes pi/6 is maximum. That means your working for derivative and double derivative is correct. Second point is 5pi/6 Double derivative is -2cos(x) Plug in the value. -2cos(5pi/6) [5pi/6 is 150] Absolute value of cos 150 is -undrt3/2 Therefore -2(-undrt3/2) will...

    Mathematics: Post your doubts here!

    Equation of the tangent y = mx + c c will be 0 since the tangent passes through origin. gradient(Differentiate the equation of curve) You will get e^x(3 -x) Plug in the values. y = mx + c [c = o & y = (4-x)e^x] (4 - x)e^x = e^x(3 - x)x + 0 (4 - x)e^x = e^x(3 - x)x e^x cancels out. 4-x =...

    Make a triangle ABO. Make a line in between. This line will bisect angle AOB Label the end of this point D Find AD using cos. cos(x) = AD/r AD= rcos(x) So AB will twice of AD Which is 2rcosx AB =AC =2rcosx Now make another triangle ABN; N being the second corner of shaded region on the...
