A parallel equation has to have the same slope so:
y=1/2x-2
is a parallel line
Question:<u /> <em>Simplify the trigonometric expression sec</em><span><em>Өcos</em></span><span><em>Ө.</em></span>
For each of the three basic trig functions, (sin, cos, tan) there are three more which act as their reciprocals. (csc, sec, and cot respectively)
Reciprocals, of course, are flipped fractions. If you have some number x, the reciprocal can be expressed as
![\frac{1}x](https://tex.z-dn.net/?f=%5Cfrac%7B1%7Dx)
.
An important property of reciprocals is that if you mutliply them together they will cancel out--take
![\frac{4}7\times\frac{7}4](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D7%5Ctimes%5Cfrac%7B7%7D4)
for example.
Since sec
<span>Ө is literally <em>defined</em> as the reciprocal of cos</span><span>Ө, it is evident that
![\boxed{\sec\Theta\cos\Theta=1}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Csec%5CTheta%5Ccos%5CTheta%3D1%7D)
</span>
First we substitute, what that means in here is that 2(c +3)
Or minus I can't see the sign but what we do is we substitute 2 with c so that becomes 2c and 2 with 3 and that becomes 6 which gives us 2c + 6 = c-13
Now we can either add 13 on both sides or subtract 6 on both sides, we can do this because they are like terms even if they are negative because they don't have any variable behind it. We will add 13 because we do the opposite of the sign you are solving some get 2c + 19 = c now we subtract 2c on both sides and we get 19 = -1c and at the end we divide -1 on both side and we get -19 = c or
c = -19.
