**If Cos Is 1/3 What Is Sin**. What is the inverse sine of 0.5? If sin θ = 3/5, find sin2θ.

Not sure how you're supposed to find this, but one way is to use the trigonometric identity of sin^2 (x) + cos^2 (x) =. You can put this solution on your website! Often, if the argument is simple enough, the function value will be written without parentheses, as sin θ.

### Sine And Cosine — A.k.a., Sin (Θ) And Cos (Θ) — Are Functions Revealing The Shape Of A Right Triangle.

Since x is in the second quadrant, the the sin. If sin a=1/3 evaluate cos a cosec a+tan a sec a get the answers you need, now! We are told that sina = 1 3.

### Trig Calculator Finding Sin, Cos, Tan, Cot, Sec, Csc.

### The Answer Is Supposed To Be Cos Θ = 2 2 3, But I Don't See.

Wanderlust1301 wanderlust1301 11.08.2017 math secondary school answered • expert. To find the trigonometric functions of an angle, enter the chosen angle in degrees or radians. Given triangle abc, with angles a,b,c;

### (Sin X + Cos X) 2 = Sin 2 + 2 \Sinx Cos X + Cos 2 X = 1 + 8 9 = 17 9 However, You Cannot Decide On The Sign Of Sin X + Cos X , Which Can Be Either 17 / 3 Or − 17 / 3.

You can put this solution on your website! Underneath the calculator, six most. Sine and cosine are written using functional notation with the abbreviations sin and cos.

### Consider The Right Oab Where O Is The Origin And Side Ab Is Opposite ∠A.

We start with the trigonometric identity: If sin θ = 3/5, find sin2θ. Adj = √hyp2 −opp2 −√32 −12 =.
