Question

Evaluate: Sin 30°- sin 90°+ cos0°/
tan 30 tan 30​

Answer 1

Answer:sin90°=1

cos0°=1

tan30°=1√3

tan60°=√3

now putting these hese value on question

so..we find

1/2-1+2×1/1/√3 ×√3

1/2-1+2/√3/√3

1-2+4/2

3/2

Answer 2

Answer:

first learn this table, then u will be able to solve these type of problems.

0° 30° 45° 60° 90°

sin 0. 1/2 1/√2. √3/2. 1

cos. 1. √3/2. 1/√2. 1/2. 0

tan 0. 1/√3. 1. √3. ND

cosec. Nd. 2. √2. 2/√3. 1

sec. 1. 2/√3. √2. 2. ND

cot. ND. √3. 1. 1/√3. 0

Step-by-step explanation:

sin 30 ° - sin 90° + cos 0° / tan 30°

: 1/2 - 1 + √3/1

ans = -5 /2
