For a video explanation , click the link 👉      DIMENSION   :           we often see the 2 dimensional, 3 dimensional objects.           for example square, rectangle, circle are 2 dimensional where as cube, cuboid and sphere are 3 dimensional objects.                                                                    but here a curiosity is that how to measure the  dimension of an object. " An object is said to be of dimension ' n ' if its boundary is of dimension 'n-1'  "   for example if we see a square which has boundary 4 lines and since each line is of one dimensional , the total object i.e.,square is of dimension 2.   similarly if we take a cube which is surrounded by 6 squares. since each square is  of...

what is an angle? : Definition #angle

Image
[For a  video explanation click the link  https://youtu.be/ejuoFUIyQJ0 ] we often use the term ' angle ' in trigonometry, geometry etc. 'Angle' plays an important role in  mathematics. Everybody know angle30,  angle  60,angle 15...etc.   But the definitition of angle is disappear. Now we see what is angle?👇                                  " ANGLE IS THE AMOUNT OF TURN OF A RAY FROM THE                                                            HORIZONTAL   LINE "                                                      The positions of rays at various angles are shown below people also...

sin30=1/2 : what it means? 🤔 #sin30, #trigonometry

For a video explanation, click the link 👉  https://youtu.be/kXOzH8k_klw      we know sin30= 1/2.     what it means ?   ðŸ¤”        In a right triangle if the sine of  angle  30  = 1/2   means that  "  the length of hypotenuse is always double the length of opposite side ". For Example ,  Suppose lenth of opposite side = 6 cm   then      lenth of its hypotenuse = 12 cm ***       Note :   If any one has any doubts in trigonometry or any mathematic concern topics please ask in the comment section .Also anybody of you want to give me friendly suggestions  post in the comment section. * what is dimension of an object? * 4th dimensional object Hypercube . * what is angle?   Page navigation #sin30 #= #1/2 #what #it #means #?  #maths #mathematics # trigonometry  #iit #jee #mains #eamcet #iit-jee #iitjee maths  #trigono...
