To find the exact value of cos(135) and sin(135), we need to use the unit circle and refer to the special angles. ... The reference angle for 135 degrees is 45 degrees, and sin(45) = 1/sqrt(2) or approximately 0.7071. Since sin is positive in the second quadrant, sin(135) = 1/sqrt(2) or approximately 0.7071. ...Free math problem solver answers your trigonometry homework questions with step-by-step explanations.The tangent function gives a value of -1 at angles of 135 degrees and 315 degrees (or -45 degrees if moving in the clockwise direction). These angles are in the second and fourth quadrants where the tangent function is negative.Calculate cos(135) cos is found using Adjacent/Hypotenuse. Determine quadrant: Since 90 135 180 degrees it is located in Quadrant II. sin is positive. Determine angle type: 135 > 90°, so it is obtuse. cos(135) = -√ 2 /2. Excel or Google Sheets formula: Excel or Google Sheets formula:=COS(RADIANS(135)) Special Angle ValuesWhat Can You Do With an Accounting Degree? What Are the Best Accounting Degrees of 2022? Here are our top 10: ; #3, The Best Online Doctorate in Accounting Programs Updated May 23,...Sine will be positive and cosine negative, resulting in sin(135°) = √{1/2} and cos(135°) = -√{1/2}. Explanation: To compute the sine and cosine of 135 degrees without a calculator, we utilize the concept of a reference angle and recognize that 135 degrees is located in the second quadrant of the coordinate system. The reference angle in ...Simplify sin(135 degrees ) Step 1. Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Step 2. The exact value of is . Step 3. The result can be shown in multiple forms. Exact Form: Decimal Form: ...The value of sin 135 degrees in fraction is 1/√2 or 0.7071. Now, using conversion of degree into radian we get, θ in radians = θ in degrees × (pi/180°) 135 degrees = 135° × (π/180°) rad = 3π/4 or 2.3561. sin 135° = sin(2.3561) = 1/√2 or 0.7071. Also check . cos 450 degree. sin 25 degree. tan 40 degreeHow to derive the trigonometric function values of 30, 45 and 60 degrees and their corresponding radian measure. Cofunction identities are also discussed: sin θ = cos(90° - θ) ... Find cos 90, tan 90, sin 630, sin 135, tan (-405), sin 210, tan (-30). Show Video Lesson. Trigonometric Functions Of Special Angles, Part 2. Example:Step 2: Compute the exact value of sin 150 °: We can find the value as. sin 150 ° = sin 180 °-30 ° = sin 30 ° ∵ sin 180-θ = sin θ = 1 2 ∵ sin 30 ° = 1 2. Hence, the exact value of cos 150 ° =-3 2 and sin 150 ° = 1 2.Given, sin 270 ∘ can be expressed as, sin 270 ∘ = sin (180 ∘ + 90 ∘) Since sin is a periodic function of time period 2 π, also negative in third quadrant or sin (π + θ) = − sin θ,where π = 180 ∘. Therefore, sin 270 ∘ = sin (180 ∘ + 90 ∘) =-sin 90 ∘ =-1 ∴ sin 270 ∘ =-1 Hence, the value of sin 270 ∘ is-1.The exact values of the six trigonometric functions for the angle 330 degrees are: sin(-30) = -1/2, cos(-30) = √3/2, tan(-30) = -√3/3, csc(-30) = -2, sec(-30) = 2√3/3 and cot(-30) = -√3.These values represent the ratios of the side lengths in a right triangle formed by the angle -30 degrees on the unit circle.Learn how to use the identity sin (A + B) = sin A cos B + cos A sin B to calculate sin 135. The answer is sin 135 = 1 2. See more questions and solutions on compound angles …Arcsine calculator to easily calculate the arc sine (inverse sine) function arcsin(x) in degrees and radians.
