    trig

    find the max and min values of the expression (2-sin@)/cos@ for 0<_@<_pi/4 and state the values of @ for which they occur i obtain pi / 6 but am not sure how to get @ = 0 as well, and you have to double diff to show max min right, full working please

    lol nice, need help on one more but it has a diagram. If you have cambridge maths 3u year 11 textbook its on, ex 14H , q 18 a). Otherwise, try use this info i give you >< PQ is a diameter of the circle and S is a point on the circumference. T is the point on PQ such that PS = PT. Let angle SPT...

    thats what i did but the answer is pi because common sense will say 0 degrees will give no area. But i think i get it now, you absolute value the cos@ to obtain pi
