Question

find the value of tan45°.cot45°-sin90°.cos90°​

Answer 1

Answer:

1 is the answer

tan 45=1 all are one

Answer 2

$1.$

Step-by-step explanation:

# Tan 45° = 1.

# Cot 45° = 1.

# Sin 90° = 1.

# Cos 90° = 0.

$\tan45°. \cot45° - \sin90°. \cos90°$

$1 \times 1 - 1 \times 0$

$= 1 - 0$

$1.$
