Web• know how to ﬁnd the cos, sin and tan of π 6, π 4 and 2; • know how cos, sin and tan functions are deﬁned for all real numbers; • be able to sketch the graph of certain trigonometric functions; • know how to diﬀerentiate the cos, sin and tan functions; • understand the deﬁnition of the inverse function f−1(x) = cos−1(x). WebIf you do not want to deal with division, otherwise you can use tan ( x), the task is possible with multiplication only. Take the small m and sin ( m) ≈ m = x 0 cos ( m) ≈ 1 − m 2 2 = y 0 Then have: M 2 0 = [ y 0 x 0 − x 0 y 0] M 2 k + 1 = ( M 2 k) 2 this is just based on duplication formula for sin ( x) and cos ( x)
