We know, using radian to degree conversion, θ in degrees = θ in radians × (180°/. Oct 24, 2015 cos( 9π 4) = √2 2. Web the value of sec pi/4 in decimal is 1.414213562. ( 9π 2)⋅ 180° π ( 9 π 2) ⋅ 180 ° π cancel the. Multiply by 180, divide by π. Web ⇒ 9pi/4 radians = 9pi/4 × (180°/pi) = 405° or 405 degrees ∴ sin 9pi/4 = sin 9π/4 = sin (405°) = 1/√2 or 0.7071067. Web find the quadrant of the angle (9pi)/4 9π 4 9 π 4 convert the radian measure to degrees. Web convert from radians to degrees (4pi)/9 | mathway trigonometry examples popular problems trigonometry 4π 9 4 π 9 to convert radians to degrees, multiply by 180 π 180. Web π radians = 180°. For sin 9pi/4, the angle 9pi/4 > 2pi.
Web ⇒ 9pi/4 radians = 9pi/4 × (180°/pi) = 405° or 405 degrees ∴ sin 9pi/4 = sin 9π/4 = sin (405°) = 1/√2 or 0.7071067. ( π 4)⋅ 180° π ( π 4) ⋅ 180 ° π cancel the common. For sin 9pi/4, the angle 9pi/4 > 2pi. Subtract this number from your initial number: Determine the coterminal angle of π/4 solution: 405° 405 ° for angles greater than 360° 360 °, subtract 360° 360 °. Oct 24, 2015 cos( 9π 4) = √2 2. 420 ° − 360 ° = 60 °. Web 360 ° × 1 = 360 °. Web 1 radian = 57.29 degree so 3.5*57.28=200.48 degrees now you need to add 360 degrees to find an angle that will be coterminal with the original angle: We know, using radian to.
