♣♠ Magnanimous ♣♠ Resonance did a good job. With help of Dharmendra sir notes I am able to solve hardest questions of A2 level. We were wrong possibly. He taught us A2 syllabus.
But now its useful. I solved this when I started my AS.

In short, we were wrong. Eh?Resonance is helping me in Biology a lot
CBSE biology syllabus is ALMOST TOTALLY different than As and A level but I am able to do it
I am getting till Sin−1 (1/3) but not that 2.8 Why?Can someone help me with this question?

Q11 (V)
The function g : x → 4 − 3 sin x is defined for the domain 1/2π ≤ x ≤ A.
(iv) State the largest value of A for which g has an inverse.
(v) For this value of A, find the value of g−1.
Thanks!
iv)I am getting till Sin−1 (1/3) but not that 2.8 Why?
RoOkaYya G and Rutzaba help.
ZaqZainab its P1 help.
n this happens at max n min point only
Thanks.iv)
value of A is the nxt value of turning point i.e 3pi/2
this is coz it is a 1-1 function (g has an inverse) so line y=k cuts the graph at one place only
v)
4-3sinx=3
-3sinx=-1
3sinx=1
sinx=1/3
key angle = sin inverse (1/3) =0.340
x = pi - 0.340 = 2.80 u do this coz limit is b/w 0.5 pi to 1.5 pi hence its found in 2nd quadrant
welcome kiddoThanks.
Correct.Sahi bat hain
But jo hota hai ache ke liye hota hain
