The most common "special angles" are 0º, 30º, 45º, 60º and 90º There is a very easy mnemonic for learning their sin and cos values (tan = sin/cos, does not need to be learned independently) If sin θ = √3/2, find the value of all Tratios of θ If sin θ = √3/2, find the value of all Tratios of θ Pawan Prajapati, 9 months ago Grade12 × FOLLOW QUESTION We will notify on your mail & mobile when someone answers this questionSine calculator online sin(x) calculator This website uses cookies to improve your experience, analyze traffic and display ads
What is the value of sin, cos, tan, cot at 0, 30, 45, 60 & 90 degrees?What is the value of sin¹ (–√3/2)?Here is the table with the values of trigonometric ratios for standard angles Trignometry Table of sin, cos, tan, cosec, sec, cot is useful to learn the common angles of trigonometrical ratios are 0°, 30°, 45°, 60°, 90°, 180°, 270° and 360°
Yes, sin1=√3/2 As, we can write sin1=sin (180–60) sin (180–60)=sin60It means that, sin 60 = sin 1 = √3/2 Method 1 Another method to find the value of sin 1 degrees is by using the other angles of the sine functions such as 60 degrees and 180 degrees which are taken from the trigonometry tableSin A sin B = sin 30° sin 60° = 1/2 √3/2 = 1√3/2 Since the values obtained are not equal, the solution is false (ii) True Justification According to the values obtained as per the unit circle, the values of sin are sin 0° = 0 sin 30° = 1/2 sin 45° = 1/√2 sin 60° = √3/2 sin 90° = 1 Thus the value of sin θ
