Practice Makes Perfect. x 2 + y 2 = 1 2.047 radians. sin -1 (3) means the angle whose sine is 3.2, 14 Find the values of sin (π/3 −"sin−1" (−1/2)) is equal to (A) 1/2 (B) 1/3 (C) 1/4 (D) 1 Solving sin-1 ((−𝟏)/𝟐) Let y = sin-1 ((−1)/2) y = − sin-1 (1/2) y = − 𝛑/𝟔 We know that sin−1 (−x) = − sin −1 x Since sin 𝜋/6 = 1/2 𝜋/6 = sin−1 (𝟏/𝟐) Thus, sin− Free Pre-Algebra, Algebra, Trigonometry, Calculus, Geometry, Statistics and Chemistry calculators step-by-step Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. Find the Value Using the Unit Circle sin (1/3) sin( 1 3) sin ( 1 3) The unit circle can be used to find the values for exact angles. [−90° ,90° ] Hence, y = 108° not possible Now, sin y = sin (108°) sin y = sin (180° - 72°) sin y = sin (72°) sin y = sin 𝟐𝝅/𝟓 Hence, y = 2𝜋/5 Which is in the range of sin-1 i. Each of … Trig calculator finding sin, cos, tan, cot, sec, csc.88/30. Since sin(-pi/3)=-sqrt{3}/2, we have theta=sin^{-1}(-sqrt{3}/2)=-pi/3. Figure 4 The sine function and inverse sine (or arcsine) function.0 = x spets erom rof paT . Find the value of sin−11 s i n − 1 1 in radian. Take the inverse sine of both sides of the equation to extract x x from inside the sine. Enter a problem Cooking Calculators.866, then sin -1 (-0.4 Ptolemy's theorem. ∫ 01 xe−x2dx. The symbol for inverse sine is sin-1, or sometimes arcsin. Similarly using the same concept the other results can be obtained. this means that a is equal to 1 and c is equal 3. But 1 2 is just 1, so:. In the … Sine and cosine are written using functional notation with the abbreviations sin and cos. Example 6 Find the value of sin−1 (sin 3π/5) Let y = sin−1 ("sin " 3π/5) sin y = sin (3π/5) sin y = sin (108°) But, Range of sin−1 is [(−π)/2, π/2] i. Scientific Calculator.. sin: sine of a value or expression : cos: cosine of a value or expression : tan: tangent of a value or expression : asin: inverse sine (arcsine) of a value or expression : acos: −1 for values less than 0, otherwise 1 : round: round to nearest integer : floor: Returns the largest (closest to positive infinity) value that is not greater 3.
