The importance of finding new sources of energy,Are we are running out of resources on our planet. There are so many resources that are reusable. an ones that only have a certain amount of an we are running out of it. so if we find new sources of energy we could save our planet it an stop it from wasting an killing out planet

If tanA+cotA=2 then find the value of cosA

aniked [119]

Answer:

cos A=

$\frac{1}{ \sqrt{2} }$

Step-by-step explanation:

We know,

cotA=

$\frac{1}{ \tan(a) }$

Substituting the value of cot A in the given equation, we get

$\tan( a) + \frac{1}{ \tan(a) } = 2$

$\frac{{ \tan }^{2} a + 1}{ \: \tan(a) } = 2$

${ \tan }^{2 \: } a \: + 1 = 2 tan \: a$

${ \tan }^{2} a - 2 \tan \: a + 1 = 0$

$( \tan \: a - 1) {}^{2 } = 0$

$\tan \: a - 1 = \sqrt{0}$

$\tan \: a = 1$

$\tan \: a \: = \tan \: 45$

$a = 45$

$\cos \: a = \cos \: 45$

$\cos \: a = \frac{1}{ \sqrt{2} }$

What are the sine, cosine, and tangent of Θ = 3 pi over 4 radians?

inysia [295]

Notice the "x" and "y" coordinates

the x-coordinate is well, the cosine value
the y-coordinate is well, the sine value

now the tangent

$\bf tan(\theta)=\cfrac{opposite}{adjacent}=\cfrac{y}{x}\\\\
-------------------------------\\\\
tan(\theta )=\cfrac{\frac{\sqrt{2}}{2}}{-\frac{\sqrt{2}}{2}}\implies tan(\theta )=-1$
