When to use trig inverse substitution and normal trig
Answers
Answer:
NOT SURE BUT HERE GOES NOTHIN
Step-by-step explanation:
We already know about inverse operations. For example, addition and subtraction are inverse operations, and multiplication and division are inverse operations. Each operation does the opposite of its inverse.
The idea is the same in trigonometry. Inverse trig functions do the opposite of the “regular” trig functions. For example:
Inverse sine (sin−1)(\sin^{-1})(sin−1)left parenthesis, sine, start superscript, minus, 1, end superscript, right parenthesis does the opposite of the sine.
Inverse cosine (cos−1)(\cos^{-1})(cos−1)left parenthesis, cosine, start superscript, minus, 1, end superscript, right parenthesis does the opposite of the cosine.
Inverse tangent (tan−1)(\tan^{-1})(tan−1)left parenthesis, tangent, start superscript, minus, 1, end superscript, right parenthesis does the opposite of the tangent.
In general, if you know the trig ratio but not the angle, you can use the corresponding inverse trig function to find the angle. This is expressed mathematically in the statements below. HOPE THIS HELPED YOU..............
Answer:
The inverse trigonometric functions sin−1(x) , cos−1(x) , and tan−1(x) , are used to find the unknown measure of an angle of a right triangle when two side lengths are known.
