Difficult Problems

1

Solved example of Proving trigonometric identities

$\frac{\cos\left(45\right)\cdot \tan\left(45\right)+\sin\left(45\right)}{\tan\left(45\right)}=2\cos\left(45\right)$
2

Calculating the sine of $45$ degrees

$\frac{\cos\left(45\right)\tan\left(45\right)+0.85}{\tan\left(45\right)}=2\cos\left(45\right)$
3

Calculating the cosine of $45$ degrees

$\frac{0.5333\tan\left(45\right)+0.85}{\tan\left(45\right)}=2\cdot 0.5333$
4

Calculating the tangent of $45$ degrees

$\frac{0.5333\cdot 1.6167+0.85}{1.6167}=2\cdot 0.5333$
5

Multiply $2$ times $0.5333$

$\frac{0.8622+0.85}{1.6167}=1.0667$
6

Add the values $0.8622$ and $0.85$

$\frac{1.7122}{1.6167}=1.0667$
7

Divide $1.7122$ by $1.6167$

$1.0591=1.0667$
8

$1.0591$ not equal to $1.0667$

$false$
