Answers
Answer:
sin 90+ cos 60 = -0.05841631681
Answer:
-0.05841631681
Step-by-step explanation:
Trigonometry is useful for studying the measurements of the right-angled triangles which deal with the parameters like height, length, and angles of a triangle. It has a variety of applications in the real world as well. Apart from Mathematics, it has a huge range of applications in several other fields like engineering, medical imaging, satellite navigation, architecture, development of sound waves, etc. Some applications make use of the wave pattern of the trigonometric functions to produce the light and sound waves.
The table of trigonometrical will help you to find the values of standard trigonometric angles, including the cos 60 value.
The standard angles of the trigonometrical ratios are 0°, 30°, 45°, 60°, 90°.
The values of these trigonometrical ratios of standard angles are essential to solve the trigonometric problems. Hence, it is important to remember the values of the trigonometric ratios of these standard angles. In this article, we would learn about the value of cos 60, how to find the value of cos 60, etc. But before we proceed, let us late a look at the trigonometric angles in the table given below.
