How do you find the sine, cosine, and tangent values given a point on a circle? be able to provide an example

Given that a point is marked on the unit circle say it is

That meanns base of the triangle

and hight of the right angle triangle

Since it is unit circle so automatically AC=1

or you can use Pythagorean theorem to find side AC.

Now we can use ratios of sine, cos and tan to find their values as follows:

Same way you can find values of sin, cos, tan etc for any given point on the circle.

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
