    Post your AS-Level Mathematics (P1 and M1) doubts here.

    Cosx = -2/3 so, cos inverse -2/3 gives you 131.8 now you got your one theta, hence; theta + 70 = 131.8 ---> theta = 61.8 so, you get theta as 131.8 and 61.8 . Other than this, 360 - 131.8 = 228.2 as one theta so, theta + 70 = 228.2 ---> theta = 158.2 so, you get theta as 228.2 and 158.2...

    Mathematics: Post your doubts here!

    I prefer this way :¬ (x1,y1+x2,y2)/2 = (5,2) (3,6 + x2,y2) = 2(5,2) x2 = 10-3 = 7 y2 = 4-6= -2 D is (7,-2) If someone have better way do tell us, but believe me, this method neva goes wrong :) ZaqZainab Rutzaba Suchal Riaz

    Mathematics: Post your doubts here!

    Q4) Q8) i) given, f(0)=-1 so, a + bcos2(0) = -1 ; a + b(1) = -1 given f(pie/2) = 7, a + bcos2pi/2 = 7 ; a + b(-1) = 7 solve siml. eqn, you get a = 3 and b = -4. ii) Put the values : 3 - 4cos2x = 0 cos2x = 3/4 cos inverse 3/4 = 0.722 2x = 0.722 x = 0.36 and see the domain hence, pi - 0.36 you...
