Cos x sin x cos 2x

Integration of sin x cos x is a process of determining the integral of sin x cos x with respect to x. Integration of sin x cos x can be done using different methods of integration. Cos x sin x cos 2x is the reverse process of differentiation, and hence the integration of sin x cos x is also called the anti-derivative of sin x cos x. In this article, we will study the integration of sin x cos x and derive its formula using the substitution method and sin 2x formula.

Cos x sin x cos 2x

Straight away we notice that two trigonometric terms on the left hand side have 2x but there are no 2x on the right hand side therefore we realise that this question will require double angle formulae. This gives us an idea of what we are trying to make the left hand side look like. These first two steps allow us to consider how we will go about proving the identity, they are not part of the proof themselves. Starting on the more complicated side, i. It is important to lay out answers clearly and is helpful to mention what you have done at each step to get to the answer you acquire. This makes it easier for the examiner to follow your work. Finally, a common mistake with this style of question is to work from both sides and meet somewhere in the middle. This is not a good technique because for some questions you will assume something that does not work both ways. You should always pick the most complicated side and work through until you have it equal to the other side. Find a tutor How it works Prices Resources. We are now ready to prove the identity. This is what your answer should look like: Starting on the more complicated side, i. Answered by Jessica B. Find whether the two lines intersect and the coordinates of the intersection if they do.

In trigonometry, sin, cos, and tan are the basic trigonometric ratios used to study the relationship between the angles and sides of a triangle especially of a right-angled triangle. Pythagoras worked on the relationship between the sides of a right triangle through the Pythagorean theorem while Hipparcus worked on establishing the relationship between the sides and angles of a right triangle using the concepts of trigonometry. Sin, cos, and tan formulas in trigonometry are used to find the missing sides or angles of a right-angled triangle.
