I posted this question before at 7:14

I think the answer to it is 0.
cot(40) - ((sin(50))/(sin(40)) = ?
these are also degrees
steps too please.

I thought since 50+40= 90 then that part would be 1, but then how would cot 40 turn out to be 1

sin50=cos40

then

ctn(40)-cos/sin= ctn(40)-ctn(40)=zilch

thank you, now I understand

To find the value of cot(40) - (sin(50))/(sin(40)), you can follow these steps:

Step 1: Convert the angles from degrees to radians. Since trigonometric functions generally work with radians, it's important to convert the degrees to radians before performing any calculations. To convert degrees to radians, you can use the formula: radians = degrees * (π/180).

So, cot(40°) becomes cot(40 * π/180 radians) and sin(50°) and sin(40°) become sin(50 * π/180 radians) and sin(40 * π/180 radians) respectively.

Step 2: Calculate the values of sin(40), sin(50), and cot(40) using a scientific calculator or online calculator that provides trigonometric functions in radians. For example, you can use the sin and cot functions on a calculator to find their respective values.

Step 3: Substitute the calculated values of sin(40), sin(50), and cot(40) into the equation.

cot(40 * π/180 radians) - (sin(50 * π/180 radians))/(sin(40 * π/180 radians)) = ?

Replace cot(40 * π/180 radians) with its calculated value, and substitute the calculated values of sin(50 * π/180 radians) and sin(40 * π/180 radians) in the equation.

Step 4: Simplify the expression using the calculated values and perform the necessary calculations.

cot(40 * π/180 radians) = ? (Use the calculator to find the value)

sin(50 * π/180 radians) = ? (Use the calculator to find the value)

sin(40 * π/180 radians) = ? (Use the calculator to find the value)

Substitute the calculated values in the equation and calculate the expression.

cot(40 * π/180 radians) - (sin(50 * π/180 radians))/(sin(40 * π/180 radians)) = ?

Step 5: Evaluate the expression and find the final answer.

Once you have the calculated values for cot(40 * π/180 radians), sin(50 * π/180 radians), and sin(40 * π/180 radians), substitute them into the equation and evaluate the expression to find the final answer. In this case, the answer should be 0.
