Two plane mirrors are inclined at
an angle of 30°.A ray of light which
makes an angle of incidence of 50°
with one of the mirrors,undergoes
two successive reflections at the
mirrors.Calculate the angle of
deviation.
please help....its urgent
let f(x)=(√(x+(√(x+1))))
1) find D_f
2) give the equation of assymtote at point
A(0,f(o))
3) if f(x)∼ a(x−1) +b (x→1) determine a andb
4) calculate f^′ (x)
5) find f^(−1) (x) and (f^(−1) )^′ (x)
