1. 5. What is the frequency of a wave that has a wave speed of 120 m/s and a wavelength of 0.40 m

balu736 [363]

Answer:

50Hz x .10m = 5 m/s

20 m/s divided by .50m = 40Hz

80 m/s divided by .20m = 400Hz

120 m/s divided by .40m = 300Hz

340 m/s divided by 440Hz = .77m

Inverse Trigonometric Functions

They are defined as the inverse of the basic trigonometric functions which are sine, cosine, tangent, cotangent, secant, and cosecant.

The corresponding inverse functions are called arcsin, arccos, arctan, arccot, arcsec, arccsc.

These inverse functions in trigonometry are used to get the angle with any of the trigonometry ratios.

For example,

$\displayystyle \sin 30^\circ=\frac{1}{2}$

Then:

$\displaystyle arcsin \frac{1}{2}=30^\circ$

Since:

$\tan 45^\circ=1$

Or, equivalently:

$\displaystyle \tan \frac{\pi}{4}=1$

Then:

$\displaystyle arctan(1)=45^\circ$

Or:

$\displaystyle arctan(1)=\frac{\pi}{4}$
