Need help finding the missing angle

Nutka1998 [239]

Answer:

The missing dimension is

$5$

Step-by-step explanation:

The Pythagorean Theorem states that

${a}^{2} + {b}^{2} = {c}^{2} \\$

Note that c is the hypothenus (the hypothenus is always opposite to the right angle of a triangle)

Therefore

${a}^{2} + {b}^{2} = {c}^{2} \\ {12}^{2} + {b}^{2} = {13}^{2} \\ 144 + {b}^{2} = 169 \\ {b}^{2} = 169 - 144 \\ {b}^{2} = 25$

$\sqrt{ {b}^{2} } = \sqrt{25} \\ b = 5$

Therefore the missing dimension is 5

Use demoivre's theorem to show that; cos4¤ =8 cos4¤ -8cos2¤+1

ss7ja [257]

Answer:

$\cos4( \theta)=Re(\cos4( \theta)+i\sin4( \theta)) \\=Re(\cos ( \theta)+i\sin ( \theta))^4 \\ =Re(cos^4( \theta)+4cos^3( \theta)isin( \theta)+6cos^2( \theta)i^2sin^2( \theta)+4cosi^3( \theta)sin^3( \theta)+i^4sin^4( \theta)) \\cos( 4\theta) =cos^4( \theta)-6cos^2( \theta)sin^2( \theta)+sin^4( \theta) \\ =(1-\sin^2( \theta))^2-6(1-\sin^2( \theta))\sin^2( \theta)+sin^4( \theta) \\ = 1-2\sin^2( \theta)+\sin^4( \theta)-6\sin^2( \theta)+6\sin^4( \theta)+\sin^4( \theta) \\ =8\sin^4( \theta)-8\sin^2( \theta)+1$
