Sin 135 degrees
Find the value of cos 135 °: Since, cos 135 ° = cos (90 ° + 45 °) Which clearly lies in the 2 n d quadrant, where cos is negative. since c o s (90 ° + θ) =-sin θ. Thus, cos 135 ° = cos (90 ° + 45 °) =-sin 45 ° sin 45 ° = 1 2 =-1 2. Hence, the value of cos 135 ° is -1 2.The true heading = 135° The resultant ground track = 130° The true airspeed = 135 knots. The ground speed = 140 knots. Given that the true airspeed the ground speed and the wind direction and magnitude form a triangle, we have; From cosine rule, we have; a² = b² + c² - 2×b×c×cos(A) Where. a = The magnitude of the wind speed in knotc² = b² + a²(sin(γ)² + cos(γ)²) - 2ab × cos(γ) As a sum of squares of sine and cosine is equal to 1, we obtain the final formula: c² = a² + b² - 2ab × cos(γ) 3. Ptolemy's theorem. Another law of cosines proof that is relatively easy to understand uses Ptolemy's theorem:

May 10, 2015 · Explanation: Cos 135° is an angle in the second quadrant. In the second quadrant, cos is negative. cosθ = x r. cos135 = cos(180 − 45) = −cos45°. An angle of 45° is found in a right-angled triangle of sides 1:1:√2. cos45° = 1 √2. ∴ cos135° = −cos45° = − 1 √2. Note that √2 is an irrational number and cannot be given as an ... How to Find a Reference Angle in Degrees Finding a reference angle in degrees is straightforward if you follow the correct steps. 1. Identify your initial angle. For this example, we'll use 440° 2. The angle is larger than a full angle of 360°, so you need to subtract the total angle until it's small. 440° - 360° = 80° 3.Trigonometry.

The tan of 135 degrees is -1, the same as tan of 135 degrees in radians. To obtain 135 degrees in radian multiply 135° by π / 180° = 3/4 π. Tan 135degrees = tan (3/4 × π). Our results of tan135° have been rounded to five decimal places. If you want tangent 135° with higher accuracy, then use the ...
Find the value of cos 135 °: Since, cos 135 ° = cos (90 ° + 45 °) Which clearly lies in the 2 n d quadrant, where cos is negative. since c o s (90 ° + θ) =-sin θ. Thus, cos 135 ° = cos (90 ° + 45 °) =-sin 45 ° sin 45 ° = 1 2 =-1 2. Hence, the value of cos 135 ° is -1 2.sin(135°) sin ( 135 °) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. sin(45) sin ( 45) The exact value of sin(45) sin ( 45) is √2 2 … ….

sin 315 degrees = -√ (2)/2. The sin of 315 degrees is -√ (2)/2, the same as sin of 315 degrees in radians. To obtain 315 degrees in radian multiply 315° by π / 180° = 7/4 π. Sin 315degrees = sin (7/4 × π). Our results of sin315° have been rounded to five decimal places. If you want sine 315° with higher accuracy, then use the ...1 Answer. Use the trig unit circle as proof. sin300 = sin( − 60+ 360) = sin( − 60) = −sin60 = −√3 2. cos300 = cos( − 60 +300) = cos60 = 1 2. tan300 = −√3 2:( 1 2) = − √3. cot300 = 1 √3 = −√3 3. sec300 = 1 cos300 = − 2 √3 = −2√3 3. csc300 = 1 sin300 = 2.The side of our 135 degree angle intersects the unit circle at point A. So the x-coordinate of point A is the cos (135) and the y-coordinate is the sin (135). And since cot = cos/sin, the cot (135) = x/y. Now we just need to find the coordinates of point A! Since our angle is 135 degrees, the angle AOB must be 45 degrees.

The angle in radians is equal to the angle in degrees multiplied by 0.017453. For example, here's how to convert 5 degrees to radians using this formula. radians = (5° × 0.017453) = 0.087266 rad. how to beat level 12 bloxorzmelanie runtz strainiowa license reinstatement 1 degree = 0.01745329 radians, 1 degree / 0.01745329 radians = 1. We can write the conversion as: 1 radian = 1 radian * (1 degree / 0.01745329 radians) = 57.29578 degrees. And we now have our factor for conversion from radians to degrees since 1 * 57.29578 = 57.29578.
