[sin 30 cos 45 + sin 45 cos 30 ] / [cos 30 cos 45. ⇒ sin (75°) = sin (30+45)° = sin (30°)cos (45°) + sin (45°)cos (30°) = ½ × 1/√2 + 1/√2 × (√3)/2 = 1/ (2√2) + (√3)/ (2√2) \sin(\alpha) = \frac{3}{8} {/eq} for {eq}\alpha {/eq} in quadrant ii and.
The Exact Value Of Cos (45°) = √2/2.
It is in the form of sin(a+b) formula, : Find the exact value of sin (75°). Sin(30)cos(45)+cos(30)sin(45) sin ( 30) cos ( 45) + cos ( 30) sin ( 45) the exact value of sin(30) sin ( 30) is 1 2 1 2.
Sin (A+B)=Sin (A)Cos (B)+Cos (A)Sin (B) Sin (45)=Cos (45)= (2^0.5)/2 Sin (30)=0.5 Cos (30)= (3^0.5)/2.
The exact value of tan(45) tan ( 45) is 1 1. 6 find an exact value. Answer #1:the exact value is (square root of 6 + square root of 2) / 4=====answer #2:i don't think so.the sine of almost all angles is an irrational.
