Question

Sin 30- Sin 90+2Cos O
Tan 30- Tan 60​

Answer 1

Answer:

sin 30 - sin 90 + 2 cos 0= 3/2

tan 30 - tan 60 = -2/√3

Step-by-step explanation:

the first question

sin 30 - sin 90 +2 cos 0

the value of sin 30 is 1/2,sin 90 is 1 and cos 0 is 1

substituting the values, 1 /2 - 1 + 2

which is 3/2

the second question ,

tan 30 - tan 60

the value of tan 30 is 1/√3 ,and tan 60 is √3

substituting the values,

we get -2/√3
