cos(2x-пи/3)=cos(пи+2пи*n); 2х-пи/3=пи+2пи*n; 2х=4пи/3+2пи*n; х=4пи/6+пи*n.

Forgive my long delay in writing, but I have had too much work. The life of an assistant schoolmistress is sometimes challenging. I want to be with you, and by the sea, where we can talk together. I have been working very hard lately, because I want to keep up with Jonathan's studies, and I have been practising shorthand very hard. When we are married I shall be able to be useful to Jonathan, and if I can stenograph well enough I can take down what he wants to say in this way and write it out for him on the typewriter, at which I am also practising very hard. He and I sometimes write letters in shorthand, and he is keeping a stenographic journal of his travels abroad. When I amwith you I shall keep a diary in the same way, a sort of journal which I can write in. I do not suppose there will be much of interest to other people. But I may show it to Jonathan someday if there is in it anything worth sharing, but it is really anexercise book. I shall try to do what I see lady journalists dointerviewing and writing descriptions and trying to remember conversations. I am told that, with a little practice, you canremember all that goes on during a day. However, we shall see. I shall tell you all my little plans when we meet. I have just hada few lines from Jonathan from Transylvania. He is well, and will be returning in a week. I am waiting to hear all his news. It must be so nice to see strange countries. There is the ten-o'clock bell ringing. Goodbye.Your loving
