Which of the following is a solution to tan^2 x-1=0? a.45 degrees, b.120 degrees, c.240 degrees, d.330 degrees

andrew-mc [135]

Do you want a general solution or from 0 <= x < 2pi?

tan^2(2x) - 1 = 0
tan^2(2x) = 1

Take the square root of both sides,

tan(2x) = +/- 1

Two equations:
tan(2x) = 1
tan(2x) = -1

Solve each equation.

tan(2x) = 1, 2x = {pi/4, 5pi/4, 9pi/4, 13pi/4},
x = { pi/8, 5pi/8, 9pi/8, 13pi/8 }

tan(2x) = -1, 2x = { 3pi/4, 7pi/4, 11pi/4, 15pi/4 },
x = { 3pi/8, 7pi/8, 11pi/8, 15pi/8}

So for solutions within [0, 2pi),

x = {pi/8, 3pi/8, 5pi/8, 7pi/8, 9pi/8, 11pi/8, 13pi/8, 15pi/8 }

Find the coordinates of the point which divides the join of (-1,7) and (4.-3) in the ratio 2:3 ??

d1i1m1o1n [39]

<h2><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u><u>:</u><u>-</u></h2>

Find the coordinates of the point which divides the join of (-1,7) and (4,-3) in the ratio 2:3 ?

<h2><u>Solution</u>:-</h2>

Let the given points be A(-1,7) and B(4,-3)

Now,

Let the point be P(x, y) which divides AB in the ratio 2:3

Here,

<h3> ${ \bf x \: = \frac{m_1 x_2 \: + \: m_1 x_1}{m_1 \: + \: m_2}}$ </h3>

Where,

$m_1$ = 2 , $m_2$ = 3

$x_1$ = -1 , $x_2$ = 4

$\therefore$ Putting values we get,

x = $\frac{2 \: × \: 4 \: + \: 3 \: × \: -1}{2 \: + \: 3}$

x = $\frac{8 \: - \: 3}{5}$

x = $\frac{5}{5}$

x = 1

Now,

Finding y

<h3> ${ \bf y \: = \frac{m_1 y_2 \: + \: m_2 y_1}{m_1 \: + \: m_2}}$ </h3>

Where,

$m_1$ = 2 , $m_2$ = 3

$x_1$ = 7 , $x_2$ = -3

$\therefore$ Putting values we get,

y = $\frac{2 \: × \: -3 \: + \: 3 \: × \: 7}{2 \: + \: 3}$

y = $\frac{-6 \: + \: 21}{5}$

y = $\frac{15}{5}$

y = 3

Hence x = 1, y = 3

So, the required point is P(x, y)

= P(1, 3)

<h3>The coordinates of the point is P(1, 3). [Answer]</h3>

Absolute value of 2c + 8 = absolute value of 10 c

Radda [10]

-2c - 8 = -10c
+2c +2c
-8 = -8c
divide by -8
1 = c

2c + 8= 10c
-2c -2c
8 = 8c
divide by 8
1 =c
