Question

find the following trignometric values
1). sin45+cos45
2). 2tan 30/1 + tan square 45
3). cos0 + sin90 + tan45​

Answer 1

Answer:

1) sin 45+cos 45

=1/√2+1/√2

=2/√2

=√2

2) 2tan30/1+tan square 45

=2.1/√3/1+1^2

=2/√3/2

=2/√3*1/2

=1/√3

3)cos 0+sin90+tan45

=1+1+1

=3

Answer 2

1) sin45⁰ + cos45⁰ = 1/√2+1/√2 = √2

2) 2tan30⁰ + tan²45⁰ = 2/√3 + 1 = 2/√3

3) cos0⁰ + sin90⁰ + tan45⁰ = 1+1+1 = 3
