tan(x)=5sin(pi/4)sin((3pi)/4)

tan (x) = 5 sin (\frac{π}{4}) sin (\frac{3 π}{4})

x = 1.19028 \dots + πn

Solution steps

tan (x) = 5 sin (\frac{π}{4}) sin (\frac{3 π}{4})

sin (\frac{π}{4}) = \frac{2}{2}

sin (\frac{π}{4})

Use the following trivial identity:

sin (\frac{π}{4}) = \frac{2}{2}

sin (\frac{π}{4})

sin (x)

periodicity table with

2 πn

cycle:

x 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} \frac{π}{2} \frac{2 π}{3} \frac{3 π}{4} \frac{5 π}{6} sin (x) 0 \frac{1}{2} \frac{2}{2} \frac{3}{2} 1 \frac{3}{2} \frac{2}{2} \frac{1}{2} x π \frac{7 π}{6} \frac{5 π}{4} \frac{4 π}{3} \frac{3 π}{2} \frac{5 π}{3} \frac{7 π}{4} \frac{11 π}{6} sin (x) 0 - \frac{1}{2} - \frac{2}{2} - \frac{3}{2} - 1 - \frac{3}{2} - \frac{2}{2} - \frac{1}{2}

= \frac{2}{2}

= \frac{2}{2}

sin (\frac{3 π}{4}) = \frac{2}{2}

sin (\frac{3 π}{4})

Use the following trivial identity:

sin (\frac{3 π}{4}) = \frac{2}{2}

sin (\frac{3 π}{4})

sin (x)

periodicity table with

2 πn

cycle:

x 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} \frac{π}{2} \frac{2 π}{3} \frac{3 π}{4} \frac{5 π}{6} sin (x) 0 \frac{1}{2} \frac{2}{2} \frac{3}{2} 1 \frac{3}{2} \frac{2}{2} \frac{1}{2} x π \frac{7 π}{6} \frac{5 π}{4} \frac{4 π}{3} \frac{3 π}{2} \frac{5 π}{3} \frac{7 π}{4} \frac{11 π}{6} sin (x) 0 - \frac{1}{2} - \frac{2}{2} - \frac{3}{2} - 1 - \frac{3}{2} - \frac{2}{2} - \frac{1}{2}

= \frac{2}{2}

= \frac{2}{2}

tan (x) = 5 \cdot \frac{2}{2} \cdot \frac{2}{2}

Simplify

5 \cdot \frac{2}{2} \cdot \frac{2}{2} : \frac{5}{2}

5 \cdot \frac{2}{2} \cdot \frac{2}{2}

Multiply fractions:

a \cdot \frac{b}{c} \cdot \frac{d}{e} = \frac{a \cdot b \cdot d}{c \cdot e}

= \frac{2 2 \cdot 5}{2 \cdot 2}

22 \cdot 5 = 10

22 \cdot 5

Apply radical rule:

a a = a

22 = 2

= 2 \cdot 5

Multiply the numbers:

2 \cdot 5 = 10

= 10

= \frac{10}{2 \cdot 2}

Multiply the numbers:

2 \cdot 2 = 4

= \frac{10}{4}

Cancel the common factor:

2

= \frac{5}{2}

Apply trig inverse properties

tan (x) = \frac{5}{2}

General solutions for

tan (x) = \frac{5}{2}

tan (x) = a \Rightarrow x = arctan (a) + πn

x = arctan (\frac{5}{2}) + πn

x = arctan (\frac{5}{2}) + πn

Show solutions in decimal form

x = 1.19028 \dots + πn

cot (θ) = - \frac{12}{5}

2 - 23 tan (x + \frac{π}{3}) = 0

(cos (x))^{2} = 0

tan (x) = \frac{2}{8}

sec^{2} (x) tan (x) = 2 tan (x)
