Example 3 Show that sin1 2x1𝑥2 2 sin-1x Solving LHS.

Sin x cos x. We see sine curves in many naturally occuring phenomena like water waves. Graphs of y a sin x and y a cos x by M. When waves have more energy they go up and down more vigorously.

A half turn or 180 or π radian is the period of tanx sinx cosx and cotx cosx sinx as can be seen from these definitions and the period of the defining trigonometric functions. Solve the integral - ln u C substitute back ucos x - ln cos x C QED. Tan x dx - ln cos x C ln cos x-1 C ln sec x C.

The equation x sin y defines y as a multiple-valued function of x. Sin1 2x 1𝑥2 Putting x sin θ sin1 2 sin θ 𝟏𝒔𝒊𝒏𝟐 θ sin1 2 sin θ 𝒄𝒐𝒔𝟐 θ sin1 2sin θ cos θ sin1 sin 2θ We need to make 2x 1𝑥2 in terms of sin When we get 1𝑥2 we put x cos θ or sin. This function is the inverse of the sine and is symbolized Arc sin x.

The inverse functions of the cosine tangent cotangent secant and cosecant are defined in a similar way. Tan1 cosx sinx cosx sinx 0 x π tan1 cosx sin. Alternate Form of Result.

They are Arc cos x Arc tan x Arc cot x Arc sec x and Arc csc x. Ex 22 8 Write the function in the simplest form.
