Answer:
√3/2
Step-by-step explanation:
If Sin theta = 1/2
Theta = 30 degrees
sin 30 = 1/2
So
Cos 30 = √3/2

Answer:
cos ∅ =
Step-by-step explanation:
∵ Sine ∅ =
From the above data P = x , H = y.
By using the phythagoren theorem, we can obtain the value of B.
H² = P² + B²
y² = x² + B²
B² = y² - x²
B = √(y²-x²)
So, Cos ∅ = B/H
Therefore the value of Cos ∅ =
SOME IMPORTANTE FORMULAS-
· Sin ∅ =
· Cos ∅ =
· Tan ∅ =
· Cosec ∅ =
· Sec ∅ =
· Cot ∅ =
{ Where , P = perpendicular
B = base
H = hypotenus }
