sin210

Calculate sin210° Determine quadrant: Since our angle is greater than 180 and less than or equal to 270 degrees, it is located in Quadrant III In the third quadrant, the values for tan are positive only, Determine angle type: 210 is an obtuse angle since it is greater than 90° sin210 = -1/2

How to find the value of sin 210

Answer 1 of 6: You can use sum/difference identities, breaking up the angle into any you’re familiar with: sin120 + 90 = sin120cos90 + cos120sin90

Sin210 = sin 180+30 And ,The formula of sin A+B= sinAcosB + cosAsinB So, sin180+30 = sin180cos30+ cos180sin30 …………………………,= 0√3/2 +-15This method can be used to find the value of trigonometric functions , Another option is to find the answer with the use of a scientific calculator11You can use sum/difference identities, breaking up the angle into any you’re familiar with: [math]sin120 + 90 = sin120cos90 + cos120sin901First express the reflex angle 210 degrees in terms of its acute equivalent in trigonometric ratios, In other words the angle formed with x-axis af1Sin 210=sin90+120=cos 120 Now, cos120=2cos^2 60-1=2×1/4-1=1/2-1, So cos120=-1/21How can I find the value of sin 210? Use a reference angle, 210 = 180 + 30 so 30 degrees is the reference angle sin 30 degrees = 1/2 P210 degrees0using the formula sin90+θ=cosθ so as per our question sin120 can be written as sin90+30 i,e sin120=sin90+30 here comparing this with above fo21Distance b/w two points is equal to saqure root of x2-x1^2 +y2-y1^2 Here x1=8, x2=0, y1=-4, y2=a Distance =10 So 100=0–8^2+a+4^2 100=64+a^29Cosecant is the reciprocal of sine, The sine of 210 degrees is the same as -1sine of 30 degrees The sine of 30 degrees is based on a 30–60–90 t1The last statement, sin-x = -sinx, is indeed correct, We can use the unit circle identities to show that if we have a point cos x, sin x on t1

How to find the exact value of sin 20° without using

Answer 1 of 6: Why do people use the word exact so casually, I can tell you there is no exact answer to sine 20 degrees I assume you want degrees, not the usual mathematical radians, Its a real number and has unlimited digits, You can’t get it with a calculator, OK, lets make a presumptio

You should be able to find it using the trig identity: [math]\sin3x= 3\sinx – 4\sin^{3}x[/math] I assume this is derived from the identity:35Check out the Quora question “How do I find the value of sin 10°, 20° and 15°?”, It shows an example of the Precise-Rewritten method for finding th6by using the expression of sine This is a convergent series where x is in radians,3Before there was calculators, there were tables, you could use a table, So if you were making the tables, or you wanted more digits than the table3Precise-Rewritten method Sin 20 degree = √2 -√2 + √2 -√2 + √2 + √2 -√2 + √2 + √2 -√2 + √2 + √2 -√2 + √2 + √2 -√2 + √2 + √2 -√2 +4Why do people use the word exact so casually, I can tell you there is no exact answer to sine 20 degrees I assume you want degrees, not the usua14Any calculator would give you the value of sin20 using the Taylor expansion of sinx, We are not going to do that 😛 Instead we will be using a33So, we want the value of [math]sin10^{\circ}[/math] without using calculator, or at least not just directly plugging into calculator’s inbuilt [m4You can use calculator for it OR Use the identity Sin3x = 3Sinx – 4Sinx^3 And put x = 10° and solve the cubic for getting sinx, Answer is = 0,1733For sin 10°, Let A = 10° This makes, 3A = 30° Now if we take sin both sides, we have sin 3A = sin 30° sin3A = 0,5, now we know, sin 3A = 3sinA – 4s2

Value of Sin 180 – Formula, Sine Value Table, Sine 180

The exact value of sin 180 is zero, Sine is known to be one of the primary trigonometric functions which help in determining the angle or sides of a right-angled triangle, It is also called trigonometric ratio, If theta is an angle in a right-angled triangle, then sine theta is equal to the ratio of perpendicular and hypotenuse of the right triangle, To be noted the value of sin 0 is also
