Introduction to Trignometry

Introduction to  Trigonometry
Trigonometry is greek word,which mean to measure the sides and angles of a triangle.If we know one of the angle of a triangle and one of its side,it is easy to calculate the other sides and other angles...
We can divide trigonometry in following parts for better understanding of the topic.
  1. Trigonometric Ratios
  2. Trigonometric Angles-
    1. Complementary Angles
    2. Complex Angles
  3. Trigonometric Identities or Pythogorean Identities
  4. Angle Transformation Formulae
  5. Common Formulae

Trigonometric Angles

Trigonometric Angles Trigonometric angles are very easy to learn if u follow some of these steps- From the table ,just learn the values of sin θ  upto 90 and now see that as now move from left to write in sin θ ,the same values will come when you move from right to left in cos θ .Now the next column is of tan θ ,we know that tan θ =sin θ /cos θ ,so we can easy calculate by dividing sin θ  and cos θ .Then next we move on to cot θ ,which can be find out by doing inverse of tan θ  or by dividing cos θ  and sin θ ,as cot θ =1/tan θ  or cot θ =cos θ /sin θ .now go to sec θ ,it is reciprocal of cos θ ,cos θ =1/cos θ ,and at the end it is cosec θ ,which can be find out by finding reciprocal of sin's value,as cosec θ =1/sin θ . Angles can be c omplementary angles and complex angles

X would most likely be in the same group of the Periodic Table as Answer:  (b) X would most likely be in the same group of the Periodic Table as magnesium (Mg). Question 15: Which element has (a) two shells, both of which are completely filled with electrons? (b) the electronic configuration 2, 8, 2? (c) a total of three shells, with four electrons in its valence shell? (d) a total of two shells, with three electrons in its valence shell? (e) twice as many electrons in its second shell as in its first shell? Answer:  (a) Neon has two shells, both of which are completely filled with electrons (2 electrons in K shell and 8 electrons in L shell). (b) Magnesium has the electronic configuration 2, 8, 2. (c) Silicon has a total of three shells, with four electrons in its valence shell (2 electr...
