1 answer:

4 0

$(sinx+cosx)/cosx*sinx= \frac{sin(x)+cos(x)}{cos(x).sin(x)} =\frac{sin(x)}{cos(x).sin(x)}+\frac{cos(x)}{cos(x).sin(x)}\\~\\~\\=\frac{1}{cos(x)}+\frac{1}{sin(x)}=sec(x)+cosec(x)$

I hope that helps!

What is the ratio of the wavelengths of these two notes? a. 5 to 4 b. 3 to 2 c. 6 to 5 d. 2 to 1

Phoenix [80]

The ratio of the wavelengths of the two notes is 2:1 option fourth 2 to 1 is correct.

<h3>What is wavelength?</h3>

The wavelength is the distance between two successive troughs or crests. The highest point on the wave is the crest, while the lowest point is the trough.

We have two notes

Number of cycle for blue = 8

Number of cycle for red = 4

Ratio = 8:4 = 2:1

2 to 1

Thus, the ratio of the wavelengths of the two notes is 2:1 option fourth 2 to 1 is correct.
