Question

Sin45+cos45-tan45-cot45

Answer 1

√2-2

Step-by-step explanation:

1/√2+1/√2-1-1

=2/√2-2

=√2-2

Answer 2

Step-by-step explanation:

$\sin45 = \frac{1}{ \sqrt{2} }$

$\cos45 = \frac{1}{ \sqrt{2} }$

$\tan 45 = 1$

$\cot45 = 1$

$\sin45 + \cos45- \tan45- \cot45$

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

$\frac{1 + 1}{2} - 2$

$\frac{2}{2} - 2$

$1 - 2$

$- 1$
