Find an angle x where sin x = COS x.

Natasha_Volkova [10]

Answer:

$x = \frac \pi4 + k\pi (k \in \mathbb{Z})$

Step-by-step explanation:

If $cos\ x = 0 \rightarrow sin\ x = \pm1$ , which is obviously not a solution. At this point we can divide both sides by $cos\ x$ to get

$\frac {sin\ x}{cos\ x} = 1 \rightarrow tan\ x = 1$

which has solutions $x = \frac \pi4 + k\pi (k \in \mathbb{Z})$

Marina CMI [18]

Answer:

Simple Interest = $315

Step-by-step explanation:

The formula for Simple Interest

I = P× R × T

I=interest, p=principal, r=rate, t=time

P = $1750

R = 12% = 0.12

T = 1.5 years

I = $1750 × 0.12 × 1.5

I = $315
